Hi C., As a mother to two sons who wet the bed at night.. I know how you feel.. It's frusterating and it's also not their fault... Bed wetting happens and when my oldest started to wet, it wasn't until he was about 3 years old. I use to get so mad, but had seeked out help... It's a sleeping disorder and no matter what you give them to drink before bed you cannot control it.. Limiting there drinks before bed will help but it's not the cure... They do have alarms out there that they recommend to use on the bed and sounds off when they start to pee.. But she is only three and most of the time they will outgrow it.. I wouldn't worry to much about it until they hit school age and more so when they do sleep overs. It can cause self esteem issues, so just be there for them and and tell them it isn't their fault.. But mostly they will outgrow it... In the mean time, coupons for pull-ups help a lot.
