Help! Have 3 yr old identical twin girls. Started potty training nearly a year ago and what a nightmare. 1 has nearly mastered it, 1 had to go back into pull ups after a summer of constant pooey pants and have now put her back in pants in the last 2 weeks. She is peeing very successfully but refusing to poo at all. The result is that she holds it in for 2 days and we then have a day of constant dirty pants as she cannot keep it in any longer and it comes in small installment! Have tried absolutely everything from star/sticker charts to rewards of games/trips etc, massive praise the odd time she has done something in the loo but am at my total wits end. Cannot put her back in pull ups as she has made big progress with the pees, but it is becoming a huge prob at nursery etc. Desperate for any advice. At the moment am taking her to the loo at regular intervals to try to avoid the whole dirty pant scenario but I am at the end of my tether and cannot see a light at the end of the tunnel.
