I know Teagan isn't yet 3 months old, but I really think she might be starting teething! She's been a bit cranky (not bad, but she's normally a really happy baby so I can see the difference) drooling like a fiend, and off and on her cheeks get really red. My friend who has an almost 8 month old who's popping out teeth like mad right now has the exact same look to his cheeks, red on the round part of the cheek and slightly chapped feeling. She also seemed really happy yesterday when Magnus was rubbing her gums with a washcloth. I feel bad for her, she's not figured out grasping something and pulling it to her mouth, so she can't chew on anything other than her hand to make it feel better.
