Anyone with any hints/tips? My ds is 2 1/2 and just put him in pants today for first time I dont really want to use a potty and my dd didnt use one at all but he gets upset when i put him on the toilet even with a toddler seat - should i persevere? also is it best to teach them to stand up or sit down to wee?! could get a step but he is a bit little really.... he starts pre school in a couple of weeks so really need to make a start on this! thanks in advance for any help!
