Yes, I didn't mention he was born early... honestly, he's done so well and is right up there with everything else for a 4.5 month old, we often forget he was early and that it might affect other things. He is breastfed and I guess I didn't understand that bf babies don't often work on a 4 hour schedule without solids...
So, we're going to work on getting him back to the 3.5 hour routine. Although, this doesn't necessarily explain why he can't make it through 45 minutes in a nap - which was the reason we started the whole transition in the first place. I guess we'll continue to use PU/PD and shh/pat to help him make it through his naps better. So, this was roughly the routine I was going to work for the 3.5 hour routine:
E: 7am
A:
S: 8:45
E: 10:30
A:
S: 12:15
E: 2:00
A:
S: 3:45
E: 5:30
A:
E/S (Bedtime routine): start at 7:15
DF: 11:00
I'm not quite sure on that last bit because he'd be eating again after 2 hours, but it would kind of be like a cluster feed. Any suggestions on how that could work differently? Also, I'm going to try to keep him up for 1.75 hours, but it may be only 1.5 at times. During those times, do we try to extend the nap so that he eats again at 3.5 hours? But naps shouldn't be more than 2 hours, correct? I know we'll have to help him extend his naps since he typically gets up after about 45 minutes, so I'm not exactly sure how long to extend them for... And is the other rule of thumb that they sleep about 5 hours during the day at this age?
Thanks for all your words of encouragement and help - it's been a great help!
