20 or 40 minute nap routine Q

[rksnyc]

Hi,
I'm just starting my 12 week old on an EASY routine and we are struggling with 20 and 40 minute naps an 4 wakes ups a night. When we have a short nap, how do I maintain a 3 hour stretch between feeds? For example he eats at 11:45am has some A then falls asleep at 1:15 but is up 20 minutes later at 1:35. It's not time to eat yet (should be 2:45) and he is sleepy at 2:30. Not sure how to handle this for now.  Hoping we get on track and he can start sleeping better but it's hard now. I can sometimes shh/pat to sleep for 20 minute naps but not 40.
Thanks everyone!

IIWY I would feed short before the next sleep, just make sure you have some A time before sleep or he'll start associating feeding with sleeping. Even a nappy change is enough.

At his age he should be doing around 1:20-1:30h A times so if he is doing longer than that and you are getting short nap it might be that the A time is too much for him. If it's much less than that then perhaps it's time to increase his A times gradually.
