We had a terrible time with our third child, she would never go to bed, she never seemed to be tired, we went for years, with one of us getting up for a couple of hours during the night with her, so she wouldn’t keep the whole house awake, and then would be up again at 5.00, the sleep she did get was generally in our bed
If someone had told me their child was like this, I’d have been absolutely scathing, and said it was ridiculous, but we tried everything possible, all failed!
She didn’t sleep all night till she was seven!
I’m not telling you this to scare you, I’m sure your problem is temporary, but sometimes you just have to go with it, it seems you can’t force a child to sleep!
