I don't want to leave LO overnight yet

No way should you leave a one year old with someone he hasn't yet got to know - with an aggressive dog. You would never forgive yourself if he got hurt and you have not yet seen that Mil can care for your child as you would like. No need to fall out. Just point out that in these difficult times things have changed. Carry on saying that is still early days. You feel that your baby is too young to be left. End the discussion here. I wouldn't leave a child or baby at any time with someone who had an aggressive dog Ever.

Your child your rules. Especially with the dog situation.
If she’s silly enough to fall out with you about it it will be her loss. Hopefully it won’t come to that though.

You're not in any way being unreasonable.
The dog is reason enough. How can she expect you to leave a small baby with her when she acts so irresponsibly.
She shouldn't be insisting on anything!

Susan56 said it correctly. Your baby, your rules. Stick to your guns. Wrong in so many ways - angry muzzled dog and Covid. You do not want a traumatised child that will stay with the child. You are not being unreasonable. MIL has the problem.

Reading through these comments it's pretty obvious that the majority vote is that the OP is definitely not being unreasonable, to which I agree whole heartedly. It always amazes me that so many grandparents think they have rights over their grandchildren and can decide when they can take the little ones.

Surely it's a privilege and not a right to be able to have a small child overnight?

Put your family first and if it doesn’t feel right, then just say it’s not an option and you will reconsider when your child is older. Our grandchildren did not stay over on their own until they were 5 or 6, and then only after they had visited with their parents loads of times. We left it to our daughter to decide when the time was right.
Also your MIL needs to consider whether her dog should be there when you visit. I love dogs and have one myself, but we would not put any child, (and the dog who could end up being PTS)at risk if there is a history or aggression.
Suggest you set out clear boundaries at the outset.

The dog is jealous and therefore dangerous. The house is not safe for your baby. You need to get advice about the dog from a dog expert. I think it is highly likely that the dog feels it is the top dog and owns the house and will never give way. My sisters son and DIL had to send their dog back to the breeder after their dog bit their child in the face. He is now hyperactive from the stress experienced as a baby in the household.

Well apart from the possibility of your one-year-old getting mauled by the dog and the fact that he might come back extremely insecure as he doesn’t know his grandparents very well it’s not something I would do no matter how wonderful my in-laws were or even consider. They are being extremely unreasonable.

Lesim, don’t even let them have your child for the afternoon if there’s the slightest chance they would take him to their house!!
You’ll never forgive yourself if the dog takes a chunk out of your precious child, for your own sake, as well as baby, DONT allow it! ???

With a dog like that id say no to day trips as well, because if they're out for the day and go back to house for any length of time, then the dog could still attack even just in a short time, if MiL popped to loo or something??No youre not unreasonable, just refuse.(maybe when the dog has eventually gone to doggy heaven(or hell,in his case?) I would tell her)

No I wouldn't agree to her having the baby overnight just yet for all the reasons given above. She should know better especially with an untrustworthy dog.

The very thought of leaving a one year old child with grandparents whom he hardly knows is absurd.

It isn't your fault that the epidemic has caused you to stay at home.

If he were my child, I would frankly tell my parents-in-law, or even better get your husband to tell them, that until and unless the dog is put down your son will never visit his grandparents without both his parents being there as well.

You are not being unreasonable, your parents-in-law are.

You are not being unreasonable. Perhaps if they didn’t have the dog it would be o.k but no way would I feel comfortable leaving a child with a dog like that I wouldn’t be able to sleep thinking what might happen

NO
NO
NO

You're not being unreasonable
Your little one needs to build up a relationship with the MIL before staying overnight

The dog is a major issue and the fact that the MIL puts a muzzle on it makes me think she KNOWS how dangerous it is. To be honest I wouldn't have them in the same room, let alone stay overnight in the house with it.

ps I have grandchildren and a dog

Just to add my bit to what others are saying. The dog is definitely a problem. For that reason only I wouldn’t let the grandparents look after your child. I like dogs but small children and dogs don’t mix. TBH I wouldn’t even leave a child alone with a good natured dog.
My Dil doesn’t really want us to have 4 and 7 year olds for a sleepover. I don’t know why, and have never asked.
It’s not the end of the world and I would never fall out with her about it. We don’t have a dog or cat at the moment.

The dog is the biggest problem here. No dog should be left, good natured or not, should be within reach of a toddler who might provoke it unintentionally - or intentionally. Any vet will tell you that. Children have to be much older to understand that dogs need to be handled with great care. I’m a dog lover and owner, so not biased against dogs.

i did read, true or false, but written by a vet that you should never leave a dog alone in the dame room as a baby as a babys cry it so high it does affect the dogs mood and can make some of them aggressive

I totally agree with greenfinch.

No you are not being unreasonable. The dog issue would make me not to have the child at their house without you or your husband at any time.

I used to have my 4 year old granddaughter stay over night quite often before lockdown but haven't had her since rules were relaxed (we are at different level here in the Channel Islands) She seems to have grown up at lot in the convening weeks and even though I have visited her at her new home a few times I don't yet feel ready to have her overnight. Maybe in a couple of weeks time

You are doing the right thing, let her moan. At one, baby doesn't need to be with grandparents overnight. And the dog is worrying me too. Children are too precious

In summary, there isn't one single person here, most, I imagine are grandparents themselves, who doesn't completely understand your point of view. The dog adds a whole added layer of worry quite aside as to whether or not your little boy would feel happy out of his home environment at this stage, you say he wouldn't and your judgement is more important than what your mother in law wants. Quite honestly, I loathe this sense of entitlement that washes over some when they become grandparents. Stick to your guns, if she doesn't like it, then tough!

grandma has got what she wants - why should she have what she wants, when what she wants is wholly unreasonable?

I would never dream of demanding that I had a GC overnight - all I want is the best for them all, and if, on an occasion to suit the parents, it is helpful to them to do that then I do.

OP - please do not even leave your child there during the day as long as they still own this dog. Just not safe. Children's faces are at a dog-vulnerable level - imagine if your lovely child was scarred for life. It makes me shudder to think about.

You are certainly not being unreasonable, your MIL is totally out of order. The baby is still very young and not familiar with this woman, the dog is also a real problem. Stick to your guns - you are being very kind allowing her to take the baby out for an afternoon. Your baby comes first at all times. Grandparents have no right to make demands like this.

Absolutely not...I love Dogs but I would not leave a Child with one that has gone for him previously..I think your husband needs to make it clear but sadly some people would rather just blame the spouse...Dont be bullied ♡
