My son is 8 months old, he’ll be 9 months on the 26th and hasn’t gotten his first tooth yet. Well the past few nights he’s been whining in his sleep (which he usually never does, he has slept through the night since 2/3 months old.) He also was very fussy last night a few hours before bed and he is generally a pretty “happy baby” that rarely fusses. He has what looks like a small drooling rash under his bottom lip. He felt warm this morning so I checked his temp and it was at 99.4. He seems to be chewing on his paci and bottle nipples a lot more lately. Idk he’s just been acting different/not himself the past couple days.
