Any help/advice/supportive words would be most welcome. He was doing brilliantly until about three weeks ago but is now showing absolutely no interest in this, total regression, and says no pretty much every time I suggest using the potty. He has had chickenpox and this seems to have thrown a complete spanner in his progress. If he's engaged and wants to, he's been getting on brilliantly. But we're back to sqaure one now. Feeling so much pressure from the school because he starts full time in September, and feeling like a failure because my oldest son was also late to toliet train, so definitely feeling like a crap mum.
