Spoke too soon

Well I called that one. For the past two days Brynn had reverted back to pooping in her pull up. On tuesday we met my sister for lunch and then went to Target afterwards. We had promised Brynn we would get her the Little Mermaid Barbie doll once she started pooping on the potty. So after shopping for a bit at Target, we headed home. She held the box the whole time and both the girls fell asleep on the ride home. I carried them up to their beds and Brynn woke a little asking to open her mermaid. I told her after her nap I would. She never fell back to sleep and snuck into Aidan's room to play. When she heard Molly wake up that's when she announced she pooped. I guess she didn't want to tell me she had to go since I would've found out she was out of bed. She had a meltdown when I wouldn't open her doll. I told her that she has to go on the potty again so that she can get it. She's been peeing up a storm on the potty and always asks after she goes "now I can open my mermaid"? Yesterday she pooped outside while playing hide and seek with Daddy. Maybe she didn't want to give up her good hiding spot behind the shed. Today I've probably asked her about 10 times if she has to go and to tell me when she does. She's like ok mommy, enough already. I know eventually we'll think of all this and laugh but it won't be soon enough for me!!!
