Baby shower help

My dad is having the shower at his house (my parents are divorced but coming together for this) and he said I needed to come over and discuss what I do and don't want.

So basically I would LOVE opinions/suggestions!

It'll be in May around lunch time. My mom was thinking just blue and white stuff. Thought of maybe some easy foods like chips and dips, fruits, sandwhiches, meatballs, etc. That's basically all we've talked about we just decided on the "when" but nothing in detail.
