Reason #1047 why having a second child rocks: no need to buy any new toys. Big sister's toys will do just fine.
Mia will spend ages spinning the wheels on B's doll stroller and banging her play pots and pans together. Her special favorite is Golly (B's chosen name for her doll). Mia can spend 30 minutes poking Golly in the eyes. She has those eyes that open when she's upright and close when lays down, and for some reason, they fascinate Mia. Pretty soon we'll need to get Mia a baby of her own because sibling fights are already breaking out over poor Golly the Dolly.
