First of all, I'm not a parent myself, so I hope I'm not running afoul of any rules or anything. Hopefully I can tap into some of the experience here of those who are.
I've not been to any kid birthday parties since I've been one, lol. But my friends were nice enough to invite my to their daughter's 1st birthday party, and I'm good friends with both parents, so I'd be glad to go. The invitation doesn't specify anything about gifts one way, or the other. In this case, is it proper to arrive with a gift, or no?
EDIT 10/27/15: I hope this is allowed, as I didn't want to be ungrateful, or comment on one, but not the other, but thank you all for your helpful responses! I had some ideas of what to get, knowing the couple of course, but I will ask them first (another thing I wasn't sure if it was appropriate or not).
