It doesn't actually say a size on the hat or the package, but I'd say newborn because my boy was about 4 mos old when we received it as a gift and he couldn't fit in it.
Yeah, he keeps me hopping. It's basically he says, "Jump!" and I say, "How High?" Lol but he won't get away with that for too much longer. :P Soon I can feel like I'm the boss again lol. Anyway really cute hate, even though I can't bid on it, I wish I could. :P
Thanks. I loved this hat....I got it as a gift, but couldn't use it! (I even went to our local baby shop looking for another one, and they had a different style, but he was too big for that one too!!!! 95th percentile baby boy!)
