Potty training woes

After Claire's big party we went to Grandpa Alley's lake place for a few days. We were lucky enough to have Megan and Breanna join us. They swam, made sandcastles, and caught a little fish with a bucket and kept it as their pet for a little while.

Alley was doing so well potty training - but we just can't get her to get rid of the diapers completely. She'll be excited to wear underwear and we try to reward her for going potty by a sticker or a penny for her piggy bank - yet she still has had accidents in her underwear and then asks for her diaper back. We are feeling the pressure from daycare to get her trained, as she is moving to preschool. But I think we just still need to give it some time.
