My baby started getting teeth after her first birthday and I was freaking out because all the other babies around her same age that we knew had already had like plenty of teeth. So I would just say don't overthink or think about what is usual or what's common and just be glad her teeth coming in because I was freaking out. And I just wanted any two to come in. So yeah, just don't try to overthink it. I think it's good they are teeth are coming anyway.
