My girl has the same teeth - 3 at the bottom and 2 at the top.
My littlen has 4 bottom teeth at 8 months and nothing up top 🙃 I think the top two are trying to break through, but it could still be months before we see them.
My 8 months old son has 4 top and 4 bottom. Teething has been non stop since his been 3 months 😢
I was wondering the same thing. My little boy is 8 month old tomorrow and he has 3 teeth at the bottom and the top 2 are breaking through too.
