Not too bad, thank you! She'll be five months old on Sunday, and is already pretty massive for her age (in the 91st percentile at last weigh-in). She can roll from tummy to back, and is getting close on the other way. Literally yesterday she realised she can lie on her back and push with her legs to scoot around, which looks slightly demonic, but seems fairly effective, and means I can never take my eyes off her again. Her main hobby is chewing things, though no teeth quite yet. She has developed an excellent giggle and laughs a lot at things. My only complaint is that she's still very jet lagged after flying back from Florida on Monday, so it waking up every couple of hours, which in this heat, has not helped with sleeping.
