Do you realize you are trying to fix a biological development issue? That you cannot fix?
She is not going to stop wetting the bed until her brain tells her kidneys to stop producing urine while she is asleep, she is unable to stop this no matter what you do.
I feel bad for you and your daughter since hubby has no idea she is just not able to do this.
Does hubby realize how much more expensive it will be in the long run to do all the extra laundry? The extra laundry soap, the extra dryer sheets, extra electricity to run the washing machine extra loads each and every day, the extra money for natural gas, propane, or electricity to run the dryer, even longer dryer time is used for all the heavier pillows, winter blankets and comforters. Extra laundry adds up in the long run. What is she is like a normal kid and does this until she is 7 or 8 years old. Some kids do it every night until the reach puberty. What is your life going to be like during all that time.
Pull ups are just penny's per day and only one per night is needed. They don't get up and change several times a night, they go to sleep, sleep all night, wake up and go throw it in the trash. A box of 20+ is only $15 at Walmart. It will cost you double that much per month in extra laundry costs.
Do you realize that one day you are going to be in the laundry area and surrounded by pee pee sheets, blankets, pillows, clothes, etc...and will just sit down and cry for hours because of all the extra work it causes you to do, so much that you will have nightmares about pee pee sheets coming after you???
That is the extreme of it to be sure...my friend actually had this happen to her. She just sat down and cried for about 2 hours in the middle of the bedding. Then she got up, took a shower, went to Walmart and bought pull ups. Life was so much better after that.
If hubby truly wants to make this an issue make an appointment with a pediatric urologist who will teach hubby that a parent can't make a developmental stage just happen when the parent wants it to. The doc may decide to give her medication to help but they usually just say it's a developmental thing and does not need meds.
Your child needs her rest, she needs X amount of hours of un-interrupted sleep. She will start to show signs of sleep deprivation, as you will too. So make hubby get up with her. If he truly thinks he has the answer to this then let it be his project.
BTW, limiting drinks allows the bladder to not fill up and give the urge it is full. She will never feel a half way full bladder and wake up.
But the medical fact is that the brain tells the kidney to stop producing urine while she is asleep. Along with the muscles growth/strength and bladder size, these are the things that effect bed-wetting. That is what stops the wetting at night.
