LONG POST***baby won’t sleep through the night***

So I’m scrolling through Instagram and I notice celebrity moms and their children. One in particular who claims her soon to be 1 year old sleeps 7-7 and does not wake up in the middle of the night. This triggered me- as I am about to have a 1 year old next month who still wakes up frequently.

Any other moms struggling with this? Is there anything I can do differently? I never wanted to pay for a sleep consultant more in my life. Her bed time is currently 8pm, and she wakes up to start the day around 7:30-8am. She currently wakes up about 3-4 times a night. All of which she’s just whining and crying. It gets to the point where the only thing that will make her sleep a long stretch is a full bottle. But I can’t take the erratic sleep schedule! I’m exhausted all the time 😭 can someone give me some pointers?!

Things that could be a factor:

She currently has 3 teeth coming through at once

She only drinks about half of her before bed bottle and refuses the rest

She’s room sharing with us (until she’s 1 ) because I fear SIDS

Things I’m doing:

Black out curtains

White noise machine

I allow her to CIO for a few minutes but when she gets louder I intervene.

She had 2 long naps during the day 9:30am-11:30 and 3:30-5pm.
