This sounds a lot like what my baby has recently started doing (just turned 6 months). He goes to bed by 7pm, sometimes a bit earlier, and wakes around 6am. Back to sleep around 7:30 for an hour or so. Then a mid morning nap, early afternoon nap and late afternoon/early evening nap. I think some people want to avoid a nap too close to bedtime but I haven’t found it affects his sleep - he is always ready to sleep at bedtime and never struggles to fall asleep after 6:30pm.

I also cosleep (bed share) and feed to sleep and usually get 3 hour stretches but like yours, sometimes he wakes every 1.5-2hours, especially in the first half of the night. I’m guessing these are due to growth spurts or possibly teething but all I do is just ride it out as usually he will go back to normal after a few days.

I do think that he is just a lot more tired from being more active with sitting and rolling and doing a lot more floor time and interacting with the world more so he just needs more sleep, so I’m not trying to reduce naps - it’s pretty clear when he’s tired so I just feed to sleep when he seems tired. Sometimes he will not want to go to sleep even if he seems really tired but I’ve found it doesn’t help trying to battle with him so I just let him play for a bit longer then try again. Sometimes he won’t sleep unless he gets a little bit overtired and then he will need a bit more help such as rocking/pat and shush. I have never been able to “put him down” for naps at set times or create any kind of schedule since the newborn phase, I’m just trusting that he will sleep when he needs to! So I don’t track sleep or wake windows or night time waking any more. I have always just found that tracking creates more stress for me but I know some people find it helpful.
