We're very proud to announce that as of the weekend before last (Sat August 6th, 2011) Sydney is 100% potty trained.
From a #1 perspective, she's been using the potty regularly for several weeks and sleeping in underwear.
From a #2 perspective, she's had been asking for a pull up every time she had to go. Eventually Meghan told her she wasn't buying any more pull ups. Sydney eventually relented.
It's worth noting that Sydney still isn't 100% comfortable with #2 on the potty. She requires consoling and occasionally freaks out as things start to pass (pooping has been a huge psychological issue). We're heading in the right direction though.
