DH doesn't like it but I don't think his opinion on these sorts of things is particularly accurate. It would be for her 3 month photos, so my only concern would be that the pattern wouldn't be "timeless" but I do love the colors and think it would look good in pictures.

Re: Cute or not cute?
3 months is prime time to do naked baby pictures, since laying on the belly is one of the best posing positions.
We also get a lot of little girls in cute onesies with a bow on their heads for 3 month pictures, simple seems to be the best route.
Ah, that I understand. I would stick with simple clothing wise. Around 9 months is when we start seeing Tutus and fancy things. Little sundresses are cute on the young ones.
