when my 3 month 20 days old baby sleeps the milk comes back to throat and distrubs her sleep ... can I use pillow for this problem... elevated position back and head in the pillow .. is it correct...

A. Using a pillow is not a problem of course you can use a pillow for a child if you want there is no issue in that place because pillow is going to give a little bit of height while sleeping and it would be good to sleep that the elevated position to avoid the situation
