T was naked in some, and had on a navy onesie with plaid shorts in the others. i wouldn't do any writing on anything. And our photog said stripes and patterns are ok at that age. Older, the more simple the better.
When DS was a baby he wore an heirloom gown for his pictures. MOST of the pictures were close up black and whites of his sweet little face. I prefer a layette type look on babies that age rather than "outfits".
