I became a Grandma when I was 37 too.
You may feel that you’re too young to be a grandma, I’m sure that people told you that you were too young to be a Mum at 16 too.
Surprise! You aren’t too young for either.
My eldest DC was born when I was 16.
Like you, I built a good life for us, I have a degree, a masters and both my DH and I earn good salaries.
I haven’t read the whole thread.
However, I have read your posts @Lomond.
• One of the reasons that your son is both able to spend money lavishly and assume that he will live a comfortable life is that you have given him a comfortable life. There’s nothing wrong with that, you have done exactly what I have done. But you can’t expect him to know what it is to struggle. I’m assuming that, like me, you kept any financial struggles well away from your DC.
• You say that his girlfriend trapped him. Hold up a second there i) it takes two to make a baby, your son could have used a condom. He didn’t. Don’t deflect all of your frustration and upset onto the girlfriend. She didn’t ‘trap’ him, the uncomfortable truth is that he ‘trapped’ himself. Besides, when you had your son at 16 didn’t people, even those whispering behind their hands, say that you ‘trapped’ your boyfriend? It’s certainly something that people said about me at the time, which was laughable as I came from a wealthy household and would have been much more comfortable where I was.
• At the moment you are reacting. Take a breath, give yourself a moment. I guarantee that everything will look clearer a week or two from now. Until then, keep your counsel, think it through, talk it through with your DH. Try to imagine what you would say to a friend in a similar position. Be your own friend.
• If you don’t want or can’t have your grandchild living with you, then don’t. However, make it very clear from the beginning what you will and won’t do. If you say ‘yes’ now then change your mind that’s worse than saying ‘no’ now.
• Your grandchild will be a whole, new individual. Your relationship with them will be individual too. I would be very surprised if you didn’t adore them, entirely on their own merits.
• You say that you are considering having more children of your own, you can be a grandma and have your own baby too. Why not?
• However, you do say that you have a 5 year old with ASC and that you have enough to cope with. I wonder whether you really want another baby? Or whether you just want to feel that the option is open to you? In which case yes, of course the option is still open to you.
• Finally, most importantly, you won’t believe this now - but I promise you that everything will be alright. It will all work out for you, for them, for the baby.
I’m going to bet that you absolutely adore this grandchild.
Good luck.
