Have you talked to the dr? My friends son and step-son suffer from this and it is from constipation. Part of it is psychological because they relate BM with pain so when they know it is coming they block it out because they relate it to pain. When they get really full, it often causes some wetness to occur to because the pressure on the bladder to. The doctor put them on Mirolax daily. It helps and I think I could of ended up in this same situation with mine to but I found Kondremuhl which is basically whipped mineral oil and I put it in their bottles and it helped regulate them during the formula and a lot of milk and binding foods younger years but prior to that my son was trying to hold it in. It helped mine get over the fear. You may want to try both and talk to the dr.... Hope that helps... Hers are 7 and 12 and I feel for her and you....
