started potty training today and DS 2.10 is in pants since 9.20am when he got dressed. I've been asking him if he wants to wee every 15 mins or so but its been no and no. Got him to sit on the potty about an hour ago and he's now sitting on it again watching team umizoomi but nothing and its now 12.44. He's not drank an awful lot this morning but has had a drink. Is this normal?
