Welcome to the chill baby mama club! My little boy is the same. Only cries (which is more like making loud noises lol) when he is hungry or gassy.
My daughter was this way, super quiet and calm; she is a little terror now running around the house and is loud and talks nonstop. Now my son is the complete opposite, so loud compared to his sister as a baby.
My baby rarely cried and she is just fine. I realized after the first year I didn’t really know what her cry sounded like because she so rarely did it. And when she did cry, something was seriously wrong, like teething or sickness.
How old is he? My daughter wasn’t really a cryer until her wind got bad at 6 weeks. Today she had her 8 week vaccinations and she has cried a lot! She doesn’t often cry for milk though. She would eventually but I rarely let her get that hungry.
We have a baby with both problems. At night he doesn’t say a word and just sleeps which makes me a little anxious sometimes. During the day he gets really fuzzy sometimes and can drive both me and my husband insane. We’ve had a hard couple of days lately and I hope it passes soon. I have no advice just sympathy. Hugs to you momma you’re doing great.
My baby is 3 MO and never cries, not even when hungry. She is meeting milestones and growing like she should. No need to worry if everything else is ok!
ETA: if you are not sleeping well because you are worried about your baby at night you could get an owlet sock. It is expensive but I’m sure there’s used ones on eBay. It really gave me peace of mind knowing that if something is wrong I will get an alert, and baby still sleeps in a bassinet by my bed but it is great not to worry if she is breathing.
