Over the last 4-5 days I've noticed one of Logan's upper teeth starting to come through - a little bit more swollen gum and you can kinda see the pearly whites somewhere underneath said gum. Yesterday I was pretty sure I saw a corner of the tooth finally poke through, but wasn't positive. Jon claimed he was "super bitchy all night long" (he had Daddy-duty last night so I could take a few hours off), and fell asleep a bit earlier than usual.
This morning, Jon held him upside down so I could do an official inspection and sure enough! We have another tooth that's broken through. It's still in the beginning stages, but given our experience from the first set, I'm sure it'll be a sharp razor before we know it.
