Meanwhile, DP and I have been feeling a little trapped by the baby. She's amazing--sweet and calm and happy--but we also have to be more or less hanging out with her all the time. When do babies get big enough that they can amuse themselves without needing in-room supervision? Two? Three? Fourteen? We manage to get stuff done, but both of us feel like we never get any time to focus on things. It's such a minor complaint for all of the awesomeness that she adds to our lives, but having some kind of idea when she might be happy in a playroom (right off the kitchen, door open) so we can cook, would be amazing. That said, she has started having little rap-move dance parties with her short little arms that are the height of adorable.
DD will play for about 30 minutes or so on her own but not usually in another room yet. We live in a small townhouse though so it's not because she wouldn't do it in another room. To be honest, I don't know any kid under 4 that wants to play alone in another room. I would suggest you take turns "getting stuff done" or having time alone. Or try and set her up close by so she can see you. Also, when she gets older she can help out. DD often stands on a chair in the kitchen while we cook and chops veggies or mixes stuff, etc.
