I got the ones at the hospital, but since I'm a photographer I just did my own when she was around a week old, once all her wrinkles started to smooth out lol
2 days. She had them done in the hosptial. Then we got 10 week pictures, then 6 month pictures, then we'll get 9 month and 1 year. We just got her 6 month pictures today =)
we didn't do any until he was a month old, he was hospitalized for 3 days when he was about 2 weeks old, and after we got home and everything it took us a wile to finally go and get the pictures done. (he was born on dec 15th, so we also had christmas and new years stuff going on)
