Baby Birthday Vent

So, I get invited to A LOT of birthday parties for babies. There's another one in 2 days...for a three-year-old girl. I was also invited to her one-year and two-year parties.

Is having adult birthday parties for kids something everyone does now, or do I just have weird friends? Keep in mind that I don't have kids, and that the majority of the attendees will also be adults (not relatives) with no kids. And we'll be drinking...PLENTY. When I was growing up, only families commemorated infant birthdays. The children were given birthday parties when they were old enough to have their own friends to invite. So, all this is new and odd to me.

I admit that I really just don't want to go. I'm crazy busy and having a hard time keeping up with all my commitments (three other birthday parties- for adults- just this week) as it is without having to go to parties for toddlers who don't even know who I am. Although I like kids, I'm just not into babies; I don't want to have any and don't find them remarkable or interesting in any way (so the expectation that you must gush over babies at these parties makes me want to bolt into the woods). There is not a way to tell parents that I think these parties are ridiculous without becoming a supervillain, and I feel angry to be put in that position. This next party is even on Labor Day, which is a precious day off and already filled with things to do.

What do you think? Do you go to baby parties? Do you throw baby parties? Do you like them or find them annoying?
