Hey it’s worth checking if it could be reflux or gas? My little ones 3 months old and does the same at night due to these reasons x
My 3 mo also does this when he’s super gassy. Stretches before bed has helped us
Mine did that last night and then zzzz
This is very normal, it’s all about natural reflexes. He is so weeny still, he is just learning his own body. I didn’t swaddle my baby at all, because she moved SO much. Now she is 1 and a half and is still like a ping bong ball in the cot when she sleeps 😂. She also still moves, and wiggles when falling asleep. (She sleeps fine btw! 12 hours at night and I get sleep) you have hope, hang in there) Xx
