me too me too me too. Not words of wisdom, really, though, sorry...
Our baby is juts about 4 months old. Putting him in the cot in the daytime is impossible, he screams blue murder. If I close the blinds to make it dark it's even worse. He's always been like this, apart from the first couple of weeks after he was born, when he was very sleepy all the time.
We had got a good thing going where I'd put him on his playmat after his feed, then about 30 mins later wrap him up in a blanket and give him the dummy and he would miraculously fall asleep for up to 2 hours. But I think he only did it because he didn't realise he was expected to go to sleep, iyskwim...
I have come to the conclusion that he has just decided he does not like daytime sleep, so till he's old enough to reason with (does this happen?? Probably kidding myself) then I have to just try fooling him into sleep before he is too tired and before he realises it's happening - so he can't fight it.
Nowadays he has cottoned on to the old playmat ruse and will sleep in his pram if I push it around the flat. He never used to sleep in the pram, unless I actually went out into the street, so that's one thing.
Problem is we are coming back to the UK the day after tomorrow for a month and are only bringing the car seat rather than carry cot so no idea how we will achieve day time naps. Am hoping for a miracle...!
