Hello B.. I think you have a good idea to try to train them both at the same time. I didn't use pull-ups with my 2 yo for very long b.c she got use to the cold wet feel and didn't use the potty anymore. I would buy a toilet chair for the youngest and sit them both down every 30 min. With my now 2yo we did little songs and hand shows. The only time we did them was when she was on the potty. She would come up and ask me to do 'bumble bee song' and I would say, you have to be sitting on the potty and she would run to the bathroom. Also, she got a treat (like an M&M) every time she sat on the potty. And if she hadn't gone potty in 30 min or so, I would give her a bigger treat to eat on the potty. That way she sat there long enough to go. I would start something after work on Friday and all weekend long. Then the day care MUST follow through with what you want. You do pay their salary remember. Hope that helps.
