It could be, and teeth don’t have to come in a certain order. My baby is 7 months and has 5 teeth already Button central incisors, one lateral lower incisor, and both upper lateral incisors The upper central incisors are there and ready to popp but seem to take their sweet time
My daughter got in there and looked properly and yep!!! He’s cut through a top tooth
Yes, this is normal! My boy had his 2 bottoms come in at 4 months and the 2 tops starting poking through at the end of his 6 month!
My baby boy got his bitten two at 5 months, too two at 6 months and now he’s getting his second set of his top teeth at 7 months <3
Mine still has the lower incisors, so I don't speak from experience. But it does sound like it.
