Baby Sleep

Not sure if this is the right place to post: I have a 4 month old baby as of this week. He takes 4 naps a day, usually around 8, 11, 1, & 4. Anywhere within those hours. Depends on when originally woke up & nap lengths. His schedule is generally wake up 630am. Sleep around 7 pm. His wake windows range from 1 hour and 20 mins- 2 hours. First wake window being the shortest. He sleeps entirely through the night which is fantastic. No wakings AT ALL. We implemented TCB from the get go! Formula fed. Eats 30 oz between 6 am and 7 pm.Now that the backstory is there a little, when did you go from four naps to three? His last nap is HARD some days. Like, really fights it. But if he’s not asleep by 5, it pushes his bedtime later than I want. He’s also been waking up at 5 some mornings which I read can be because of going to bed later/ needing to drop a nap. I’m not sure how to do this because his mornings are pretty much 1 hour and 20 mins and he’s fussing. I’m fine with putting him to bed around 6 instead of 7 to get him used to it but even then that’s pushing his wake windows. Any advice!? I was thinking of trying to do three naps around 5 months, like I read, but I’m struggling with that last nap of the day. via /r/Parenting https://ift.tt/31J44dM
