Today is the first day of potty training my DS who is 2yrs 6mths. I have been taking him to the potty every half hour and so far he has done a good few wee's in his potty and has had no accidents. The longest time in between wees was about 2.5 hrs! Should I continue with every half hour or could i extend that now? Also, he hasn't asked to go to the potty or taken himself yet, is that something that he should start doing soon?
