Oh dear! Are you exhausted?!!?
We brought Harry home at 3 months, and from the very first day we made sure we played and played and played with him during the evening. After he'd finished his shots, we let him run outside and really quite wore him out....
Now, he's a 'bigger' boy - so the 'being able to hold his pee' problem has never really applied - but we've always put him to bed about 10 p.m. - and he wakes up when WE wake HIM up. When he was tiny, I would get up and take him out for his pee - then put him straight back to bed
As with babies, I think making sure they're full of good food, making sure they've enough to drink, and being totally worn out from their day is the way to make them sleep....
Good luck! Sally + Harry
