About 8 months there are signs of white spots appearing on the gum. These are budding teeth but my LO started drooling since 4 months onwards.
Sucking thumb and bringing fist to mouth is part of normal development as they are becoming aware of that part.
It depends. My lo is 3 months and already start teething.
Should have sleep problems and fussiness too
When they drool a lot also a sign of it
