C.D.
I have the same issue, except we moved our son back to diapers because I was tired of washing his sheets every morning since he leaked through his Good Night. Pampers makes a size 7 diaper that is available at a few stores- we get ours at Target. I would stop using pull ups as they aren't meant to hold a lot. They are meant for the occassional accident (my DH works for Kimberly-Clark who makes those) and even those they don't hold in well. If you can't find the diapers, then switch to Good Nights. They are meant to replace diapers for older kids. I talked to our pediatrician and many others out there and kids are not considered to be developmentally delayed in potty training at night until they are 7. I was told the part of their brain that wakes them up at night to go potty is still developing until that age. So, your son may not be able to wake himself up at night yet. I have heard people who have used those bed wetting alarms at age 7 and they worked well. I know people that set their alarms at night and wake up their kids to go potty. I, personally, am not to those points yet as my son is only 5. I want him to be trained, not myself or some alarm. I will wait until he is closer to 6.5 years old to try those measures. I don't want to medicate him, which is one option when they turn 7.
