I think it’s normal. My 6w old had it already few times.
It could be just active sleep, sometimes my baby has a whole cry and goes back to sleep in a 5 seconds span. I’d definitely keep an eye on frequency and would search for other night terrors symptoms. My sister in law had it growing up so my husband could tell the difference
Check for gas. My baby had really bad gas pains and would react more in his sleep at that age.
@Kayleah he’s woke up fully now and had a lot of gas that seemed painful to pass so that might’ve been it! X
My son started having night terrors around that age and continues to have them.. he’s 4. They were very frequent after the first time but have gotten better. Definitely let your pediatrician know though
