Not STTN yet

My 6 month old still isn’t sleeping through the night. I know it can be perfectly normal but omg I am so tired from the interrupted sleep.

We put him down for bed at 7 and he usually sleeps until some time between 1am-3am when he wakes for a bottle. Then goes back to sleep until about 6-6:30am. BUT my trouble is that at least 2-3 other times during the night he will wake either bc he’s pulled his pacifier out of his mouth or he just wakes up on his own and is just awake. He doesn’t cry at all..just lays there eyes wide open. Sometimes it takes 30-45 minutes to get him back to sleep.

I’m just exhausted. My oldest was sleeping 7pm-7am at like 12 weeks so I’m struggling lol.

Any thoughts? Tips?
