What’s your baby’s sleep like?

I have an almost 5 month old who isn’t sleeping too well at night. I can only compare him to my daughter who slept like a champ (8 hrs by 6 months). With my daughter we did sleep train, and no co sleeping. With my second now, I’ve just been putting him in bed with me and nursing him to sleep just so I can get some rest. I do exclusively breastfeed except for maybe formula twice a week at grandma’s house. His nap and sleep schedule looks like this:

7:30 AM: wake for the day
9/9:30 AM: nap 1 for about 1-1.5 hrs
1/1:30 PM: nap 2 for 45 mins if I’m lucky
4pm: final nap of the day for 30 mins maybe?
7:30 PM: bedtime
8 PM: Wakes up shortly after feeding and putting to bed- just nurse him again
11:30 PM: wakes again, I nurse him in bed and if I can stay awake I put him back in his bassinet
4/4:30 AM: wakes up and I nurse him again to sleep
7/7:30 AM: up for the day

So curious your baby’s ages, and how long they sleep for during the night. Any advice or tips to help with nighttime sleep is welcome!
