Hard time with evening naps
My 11week old won't sleep suddenly in the crib after being soothed for his last nap. The sleep environment is the same and he gets soothed the same way for every sleep. He usually takes 4 naps in the day and they progressively get harder to put him to sleep. The fourth naps he often is skipping now because he is completely alert within 10min of us laying him down. We try to put him down over and over again for that nap and he just wont sleep. Our bedtime is 730pm for him because his naps are generally 1hr or 30min and hes screaming his head off starting 430pm. We wouldnt want to put him for a nap at 430 but he is very upset starting this time. Ideally we want him asleep 430-530 and then up until 730. Before 8weeks he used to just go to sleep real easily and now we are always shushing and bouncing him to get him to close his eyes. He also wont sleep without the swaddle, we have tried really hard. The only success we have had with his fourth nap is to let him sleep on us... something we did ONCE AND DONT WANT TO DO MOVING FORWARD. Please help!
