Mr dd has 3 children.the first was very tough, he was ill for quite a long time and consequently struggled to sleep alone.My daughter said it was easier for her to sleep if he was either in bed with her or in the cot.
The second was no bother, quite well and slept in his own bed,but if his mummy went out he would go into a full on melt down until he was about 2 yrs old.no one but mummy would do.Hes grown out of it.I think he was punishing her for leaving him.
The third was a breeze except she was ill at about 2 1/2 yrs,and is now in mummy's bed and has been for the last year.my dd knows she should be in her own bed but is just too tired to do it and says no one would get any sleep.
I do what I can,loads of laundry and clearing up.i don't cook as the kids are a bit finicky and prefer mummy's food.
She says the sleep will sort itself out,and it does seem to eventually.
I hate seeing her so tired and understand where you are coming from but I have finally accepted she'll do it her way.I just help when and where I can and try not to worry,I do say Try....
