2 yo DD (nearly 3) is having problems going down at night. We have a good bedtime routine, the timing of which is dependent on whether she has had a nap. Generally we start routine (bath, stories, bed etc) about 6.30 - 7, aiming for in bed by 7 - 7.30.
She definitely goes down better if she hasn't had a nap during the day - but will have been grumpy and overtired all afternoon, and generally wakes up early (before 6) due to over tiredness.
Kind of lost as to what to do. 5 month DS is currently in our room, which is the other side of the house, but needs to be moved into his own room as he has outgrown his Moses. His room is right next to DD's with very thin wall separating them - she will keep him awake with her screaming and shouting.
Currently we are going in once to reassure her, sing a song and sometimes lie down with her for a few minutes, then leaving her unless she gets really really worked up.
Any ideas on how best to handle this? Sorry it's so long.
