I pretty much never woke her up. I can count on 1 hand the number of times she's slept in, so on those very rare occasions, I slept in too!! Honestly, once we find a good routine, she does seem to regulate somewhat so if she slept in or took long nap, I let her bc I figured she either needed a catchup for whatever reason, or was getting sick.
At that age, we did:
W 7:00
Nap 12:30 to 2:30
Bed 7:30pm
If she woke earlier than 7am, I left her in her cot til 7am. If it was super early, I would keep the morning very low key to make it to the set nap time. But, she was usually able to deal with long morning A times usually without too much issue. We counted 5hrs from nap to bed bc that's when she was prone to OT and I can't deal with a disrupted night
If she did a 1.5 hr nap, I'd put her down at 7pm. If she slept 3hrs, I'd put her down between 8 and 8:30. I'd probably have an active afternoon to wear her out and hope to have her down @ 8pm. Eventually, I nudged her nap to 1pm so lunch wasn't so rushed, probably around 2.5. I started setting the nap time for my sanity and honestly, we kept a very similar routine until 6 mos. ago when she dropped the nap. Yes, we had EWs or short naps or an occasional super early nap or bt, but overall I found that she was able to regulate herself if we stayed consistent. Doesn't work for every bub though! Just a matter of trial and error..
