I think my DD is cutting a tooth but it's not right in the front bottom... it is on the bottom but off to the side. Is this a normal spot to get a first tooth?? Could it be something else other than a tooth? It's white and hard. I was thinking of trying out cereal with her tonight (she'll be five months this week) just to see if she'll take it. She's showing all the signs of readiness on Kellymom except for sitting up unassisted (she does hold head up and sit up well if propped).
