Here’s what’s crazy... I have 3 kids and the two older ones were not allowed to sleep on their backs when they were babies. (They are 17 & 14) Now they can’t sleep on their stomachs. Everything always changes. I recommend following the current guidelines. No matter what you’ll always supervise and always wake up 100 times through the night to check on them.
If it don’t feel right tho, don’t do it.

No but u can sleep him elevated on a pillow if he’s real colicky it could help.

I did with my son cause he had bad acid reflux but it's not the best idea

I let him sleep on his stomach on my chest, co sleeping (obviously) for the 1st 3 months. Then he slept on his stomach in between my husband and I without pillows or blankets.
They say you shouldn’t, but he was 24/7, 100% supervised at all times, and it was the only way he would sleep

Here the abc of crib safety
A- alone
B- back
C- crib

No!

Babies should NEVER sleep on their stomach until they can roll back and forth on their own and hold their heads up good

Once they rolled on their stomach on their own and had good head control then I didn't roll them back

I only let mine stomach sleep after 1m supervised. He mostly did side sleeping though

No.. the doctors suggest there back to prevent SIDS.. they say don’t co-sleep with your child but I do.

No unless they are very colicky. I’ve never had to deal with that personally. Otherwise, back is best!🖤
