How can I get my almost 6 month old to start sleeping in her crib at night for bed? Her reflux is…

Does she like sleeping on her stomach?

Yeah when she does tummy time she will fall asleep on her tummy and stay asleep for awhile.

when she falls asleep in your arms put a soft pillow on her crib && lay her on her side. I hope this works

you can have her sleep in her belly & try burping the baby after every feed until you here a burp I found that's what help help my daughter with reflux.. If you want to actually have your daughter sleep though the night it's all about routine took me 1-2 weeks to have my daughter sleep through the night .. ButMake sure eating 3 meals. For us dinner around 6-630 then she plays make sure she BF in between that time we read a book around 730 go to her bed around 8 I would lay her in the bed on her belly for like 5 mins even if crying at first to get her used to the time so she know this is bed time .. Eventually ( still now in my case I BF her until she falls asleep) Then if she wakes up in the night just let her cry 5 mins go in her room tap bum 'shh' her leave room just do that over again if she doesn't fall asleep ( like my daughter didn't I piked her up & rocked her then put her down crying ) just have to keep doing the process over & over each time you leave the room stay away a little longer . But like night 5 she got it down but some nights she would wake up again & at that point I let her cry till she fell asleep. It takes hard work , patience , & routine just keep doing something every night . Hope you get everything to work out .. Sorry for such long comment just hoping it helps

I formula feed not breast feed. She sleeps through the night and has since she was about 2 months old. I just can't get her to sleep in her crib at night. When she's sound asleep then I'll put her in there but she wakes up almost instantly as I put her down.

does she sleep in her crib during naps?

Yes she sleeps in there during nap time.
