Things Rosie "needs to do" include:
She is working on buttoning and unbuttoning clothes and provisionally accepts help with that. Sometimes. Similarly with zippers - if we start them for her she can zip them, and she's good at unzipping. She can put all her hats on herself, so of course she must.
There's a lot of sitting on our hands going on while she struggles if any of these activities pose a challenge. It's gotten worse lately because she sometimes asks for help and then changes her mind and complains vociferously if we try to help. It's tough getting yelled at by your kiddo on a daily basis. And it especially hard to push her through on a schedule.
But it's also fun to see her face light up when she succeeds at doing something she hasn't done before. It looks a lot like this:
(whole series starts here.)
And at least we have this one bit of leverage; if she's delaying doing something, we threaten to do something ourselves that we know she'd rather do, and then we start counting to three. "I need to do it," she says, and just after "two," she does. Almost every time.
