It's a back wisdom tooth, I'm not sure why it cracked. Probably insufficient brushing back there. I'm sure the dentist will lecture me about the cause. It isn't deathly hurting yet thankfully as I am yet to express a drop. DS is really tiring me. No day sleeps off me and very unsettled nights. I can get him to fall asleep but he wakes within minutes of putting him down. Grunting and leg pulling. I hear abs feel his stomach gurgling. Of a night he spends a large portion of it grunting and straining like he's trying to pass wind. Also gets congested. I'm feeling so awful as my DD doesn't get much of my time, DS takes it all. Had a good cry about that earlier.

I'm so glad you found the tongue tie turtledove. It's a shame it wasn't picked up sooner. That's interesting regarding the intolerances.
