Do you do any activities with your baby yet? If so, what do you do? I say his name all the time, I spell it for him. I sing rhymes, numbers and letters. I have an app that shows colors and shapes it's very bright and he loves it. He even reaches for the screen sometimes. I'm not sure if this is doing anything so I've been wondering if I'm overdoing it, could be doing more or if this is just enough.
