When you mentioned seat, I thought.of a folding seat at CT that may work for.you. On the CT website, search for Escort stadium seat pad. Part # 76-1599-0.
This, is a thin folding seat that will not increase the center of gravity and will help keep the daughter more upright.
Thanks Teslin! I'll definitely check it out!! I want her to enjoy it out there, so keep the suggestions coming!
