ELI5— what should baby wear when bed sharing?
Context:
-baby is 6 months old
-recently moved baby to the bed between me and dad due to baby having multiple wakeups that were severely affecting my sleep/sanity
-room is kept at 76 degrees with an overhead fan on high and a stand fan on high pointed at the bed
-dad tends to be on the warmer side, but baby sleeps next to me and dad is scooched to the far side of the bed
-we have a decently firm memory foam mattress
When baby sleeps, if I have him just in a diaper, his skin all over his body feels very cool (sometimes verging in cold). HOWEVER, whatever skin is in contact with the mattress feels warm and occasionally a tiny bit sticky/clammy. It’s like half his body is slightly too hot and half is slightly too cool. Should I be putting a onesie or a light sleep sack on my baby, or leaving him just in his diaper?
