Baby is not sleeping on the back during the day

Praying someone has any tips or had a similar experience and overcame it.

Hello all,

Our now 8 week old baby is not sleeping on the back DURING THE DAY since he was around 3-4 weeks old. As soon as he is asleep and we place him on his back, he notices and opens his eyes and puts his feet up, at first okay and tries to fall asleep but as soon as eyes are closed he starts screaming a lot while crying, eyes open again, he is again sleepy and closes eyes and again crying a lot. Nothing helps him, not swaddling, not white noise, not making room darker (seems like he knows its day time which is very strange), not even being on a stroller (which sucks because we cannot go for walks withoht a carrier).

His favourite sleeping positions are on the side and on the stomach or in a carrier. This whole situation is making us frustrated because one of us has to always keep an eye on him after he is placed on the stomach or side during the day to sleep.

Thankfully during the night he sleeps on the back and does not cry.

Do you have any tips or similar experiences and what did you do?

Thank you in advance,

A desperate mother
