Charlotte is continuing to discover new tricks, like holding her own head up and looking round, smiling (intermittently (and no longer always associated with an impending fart)) and sucking her thumb when a dummy is not available.
She also seems quite chuffed with herself in relation to this last one, although it only works when she’s quite awake, so when she wakes in the middle of the night and wants a dummy she kind of forgets that she has a take everywhere option available close at hand (so to speak).
