13 more shirts!!!
Gosh, my baby only had one sock "shirt" for the first several days...... Maybe you could start a scrapbook - get some pages set up for the trip home, first day at home, first bath if you bathe him when you get him, first meal at home.... stuff like that. Boy if I shopped as much as you do, my hubby would probably tell me I couldn't even bring Summerlin home
Good luck and stay excited!
