Hi! My baby is 9 month plus old too, and sometimes he wakes up in the middle of the night while making those weird loud noise (eyes closed). For me, I will just leave him alone and monitor. Usually he will stop after a while, and then changed sleeping position. I assumed he was having some weird dreams 😂 I will only feed him if he is really hungry.
If baby wakes up and doesnt cry, its ok can just leave baby alone
