Well our son is 6 still wets the bed...has gotten better since he had his tonsils out...maybe because he was not sleeping well with all that snoring going on.
Anyway, the only way that I maintain my sanity is by getting these large tuckin mattress pad overlays from the bed wetting store. They go over the sheet. So when the kid wets the bed you simply take the overlay off, wash it instead of the the whole sheet set. I can not keep up with daily sheet changes or middle of the night sheet changes. Every night I put down three on the bed (one on top of the other). Then if during the middle of the night there is an accident, I just get up, peel off the top one. Still have two more ready to go incase of more accidents. These things are expensive...but have seriously helped me remain sane (I can not be changing sheets in middle of night). I ended up buying 12 for about $350 (get the x large tuck in ones), but I am telling you this was money well spent. You could get by with less....but this was an impulse buy for me when I was fed up at 2:00 am because I had to get up and change sheets!!!
Also my husband usually stays up until midnight and right before he goes to bed he wakes up son and has him go to the bathroom. This has been helpful...but if son does not wake up around 5 am on his own...then I am washing the overlay (which I can live with).
By the way, I wash the overlay with vinegar in the wash machine to get the smell out and disinfect the thing.
Below is the link to the bedwetting store. I feel your pain :0)
Good luck,
S.
