Less teeth than Skylar started with yesterday!

So yesterday Skylar had 6 teeth and now it is more like 5 1/3. Somehow he must have cracked his tooth. Yep, that's right! This morning both Jon and I noticed separately that one on the bottom looked slightly jagged. Tonight we had a very challenging dinner with him starting to cry very hard. I thought his teeth were bothering him (he has been really teething bad the past week or so). So I took him out and held him while I finished feeding Elaina. He was a mess so I thought it must be really bad and finally got him calmed down with some Orajel and a bath. Well, Jon was playing with him and noticed half his tooth was gone! We are calling the pediatrician tomorrow but we think he must have cracked it on something and then the teething bisquit at dinner might have just caused it to separate. The first time mom in me was freaking out. How could I not know it was cracked?!? I think there is a fine line between keeping them safe when they play (especially when they are learning to crawl, stand, walk) and being overprotective and being a nervous nelly. I want my kids to be independent and confident to try new things so I try to give them some space and recognize that falls and bumps and bruises goes with learning to do some of these things. But seriously....already cracking a tooth?!? I saw the rest of his childhood flash before my eyes and it included trips to the ER for broken bones, etc!!!
