my son is 11 months old and has 8 teeth. for the first one, he was about 5 & a half months old for his first one.
it seems like it took forever for it to come in once it broke gums. i gave him every teether imaginable and it took a little while for it to really start coming through. i would say about 3 weeks maybe or longer. i honestly dont remember exactly how long it was but it was quite a while…
