ds has never been dry at night, and always overflows his pullups. i usually lift him at 10pm. No other issues.
Have bought a wireless alarm. I was up 3 times last night to change the bed etc.
I don't think DH and I can cope with that level of disturbance for very long..... Gawd, I'm getting horrible flashbacks to the baby days 
how long should we continue? Will he dry up eventually with age anyway?
