Maybe too hot, my son used to cry very frequently in 2ndmonth; after cool to 23-24 deg, sleep like angel
Mainlanders tend to wrap up babies but in fact babies sleep much better with less clothes
So cold?
We do use air-con and set the temperature at 25 degrees. I feel the room is quite cold already as it's a small room.
Don't wrap the baby too especially the arms.
