My son has been super cranky and my husband noticed he was pushing at his cheek and chewing on one side so I risked a finger to check and his gum was SUPER swollen in one spot. But it's the molar spot so I'm wondering if his tooth is really coming in or something else happened? He's 10 months and I've got a picture labeled with the teeth he has. 1&2 came in at 4 months, 3 was 6 months, 4 were all by 8 months. Now he's almost 10 and 5 is where he's swollen? Is this normal?
