I had no idea what category to put this in so feel free to move it as needed!

My friend just had her second baby girl and I'm going to visit this upcoming weekend. She is totally on top of frozen foods, etc, but I'll probably bring something for lunch. What else can I bring? I wanna bring something for her/new baby and also something for her older daughter so she doesn't feel left out.

Suggestions? I'm clueless!
