Sleep help! Rough nights & early wake ups!

Hi! Really hoping someone can help troubleshoot!!🤞🏼Baby boy is 10.5 weeks old and we are having a couple of different sleep issues. Firstly, he’s been pretty irritable and fussy during the day. From 1-2 months old he was doing pretty good stretches of sleep at night, but lately it’s been rough. He seems to be sleeping a lot lighter, i.e. waking up fussing, squirming and whining shortly after being put down. He’s waking up and fussing almost every hour at night it seems, when he used to just wake up once or twice to be fed then put back down easily.

The other thing is, I wonder if it’s possible to push his wake up and bedtime by an hour. He’s consistently up at 5/5:30 am and will not go back down. He gets tired at night around 7 pm, and is fussy until we go to bed. Sometimes he will fall asleep in the baby carrier until I fully put him down between 8-9 pm. I would love if he would sleep until 6 or 6:30 am, and make it until an 8pm bedtime!

Other details - he contact naps, and doesn’t do too well in the bassinet during the day. Contact napping he will go 2 hours. 2-3 naps per day with the last usually somewhere around 4-6pm. Exclusively breastfed. We use the Snoo at night, keep lights off during wake ups, sound machine, heating pad to warm up bassinet.

Please let me know if anyone has any ideas to adjust! Thank you!!
