Night wakings

My son is turning 8 months on the 29th and is still waking up at night. Sometimes it’ll be a half hour after he goes down then again an hour later and again around 3am. He takes 3 naps a day about 2-2 1/2 hour wake windows. I BF and give purées throughout the day- he’s in the 85% for weight so I know he’s getting enough. Also, when I put him down at night he’ll scream for about 10 mins then fall asleep. He goes down for naps pretty well but has been crying everytime I put him in his crib at night I think since from the beginning. Any advice?? This mama needs a break!

Second nap 12ish-1

Third nap 3-3:30
