dd1 - consistently wet every night. we tried desmotabs but they had no effect at all. at 8 1/2 we borrowed an alarm, and she was dry within two weeks. it didn't wake her up to start with - we used a baby monitor so it woke us up (dd1 can sleep happily through a fire alarm), so i then went in and flung the light on, clapping and banging and generally making sleep untenable lol (small nod to the traumatised greensneeze). the idea being, that if weeing in bed has such an undesirable effect (ie noise, light, mentallist parents etc), your body learns to deal with it before it gets to the 'leak' stage. it was absolutely fantastic for dd1. she has been dry for a year now (and shows no sign of being scarred for life lol)
(oh, dd1 had been through the paed mill lol - at one point we had to measure her output so had to persuade her to wee in a pot to see how much there was etc and see if there were any issues with capacity... all a total waste of time)
ds1 - hmm. he's only 7... the paed (different paed lol - we moved) referred him for ultrasound etc which was all normal, and kept on at us to try desmotabs. as they hadn't worked with his sister we weren't keen, but after 6 months we have succumbed. so, now he's on 2 different meds (also oxybutinin to stop spasms i think?) and has an alarm as well. the meds help a little - he is definitely wetter without, and so far the alarm is only waking him up to go for a wee, rather than teaching him to wake up before it goes off. so, the jury is still out...
the paed essentially said that there are two reasons for night time enuresis
a - essentially maturity - non production of the hormone (which medication replicates)
b - really deep sleep (in which case an alrm will have the best effect)
obviously it is also possible to have a combination of both factors... which appears to be ds1...
dd2? dry day and night at 2yo lol. go figure.
so, in sum. it will depend on your particular child and the reason for bedwetting lol.
but my laundry and drynites bills are down...
(oh, the reason we decided to take ds1 earlyish (at 7) to doc - drynites not capable of containing lol, so in addition to drynites and bedmats bills, i was still doing laundry every day, including his duvet... his room literally stank like, well, you can imagine...) Very jealous of you not having to do laundry every day Ilana!
so, two down, one to go.
