My 9 week old the usually takes 2-3 decently long naps a day and much shorter naps in between if she falls asleep in the car seat or being held. She doesn’t seem to have days and nights mixed up because she has a lot of awake time in between and I always talk and play and have the house much brighter during awake time. But at night even though I try to follow the same routine and put her down drowsy she fights going to sleep and doesn’t usually sleep from until about 1130/12 even though her last nap is usually around 5 and we try to put her down starting at about 730 or 8. Also the past few days she’s started waking every few hours again to eat even though she had been going much longer stretches through the night. Any insight on this??
