I think the winddown is a major factor for us. Her bedtime routine works wonders:
bath, dim room, lotion, pjs, bottle with mobile music on, cuddles/burping, lay in crib watching mobile, swaddle, white noise, and she falls asleep on her own.
Nap routines I'm having a bit of a problem with. I can't seem to think of enough things to do. We've got a semi routine including
white noise, close blinds, diaper change, cuddles/story, watch mobile, swaddle and then I have to rock her to sleep (haven't gotten the sleep training down for naps and I again think its due to the routine)
But it seems as though its not enough. Shes still not very tired when we get to the sleep part. I can't think of what else to add in there though, except for things like bottle which obviously I don't want her to associate with sleep.
Back to A times... Yesterday she was up for four hours, don't ask me why, and took an hour and a half nap opposed to 45 minutes. After that she was back to her regular 1.5 A 45 S times.
On the bedtime, she went to bed last night at 10:30 and slept till 8 this morning. She only woke once so I consider that a mini victory!
