Baby falling asleep

Alli • Grace 10-8-18 ❤️❤️

So we got my baby the zen sleep sack and she would do really well falling asleep in it. She would lay awake, but content and fall asleep on her own. That started at like a month old. However, she’s been sleeping in her pack n play. It has a changer attachment and we had the changer up and then she would sleep in the bassinet next to it, so she’s be sleeping sideways in it so her head and toes were close to the long sides rather than how she would be in a crib. Well she’s growing and barely fits that way anymore so we took out the changer and tried putting her the other way. She will not fall asleep like she had been unless you lay her sideways like she used to be. She ends up rotating through out the night but soon she’ll be too big to lay that way, but she doesn’t seem to want to fall asleep the other. Any suggestions on how to get her used to laying normally in it?

(Hopefully this makes sense)
