Twice this week during dinner DD's mouth looked like this halfway through eating. The top and sides turned red but it didn't feel raised and there was very little on her chin. She hasn't been eating anything different - last night she had chunks of carrots & squash and a pinto bean "burger" the redness started right after the burger then I gave her some pear-apple-sauce. She got the hiccups for the first time in quite a while while she was in the tub after dinner but didn't really act strange. The other day I thought it was from beets and they just dyed her skin but she didn't have any beets last night.
