Potty Trained Child Now in Sleep Diaper

I think you may be reading way too much into this. Night time bed wetting is common among children up until 7 or 8. Sometimes it's as simple as the fact that their bladder isn't growing as fast as the rest of their bodies, or suddenly they are producing less of the enzyme that keeps us from producing as much urine at night. Put a pull-up on her and forget about it. She will grow out of it, and night time wetting will have no effect on being daytime potty trained. There is very likely nothing you or she can do about it, and making a big deal of it may make her feel ashamed. (My older daughter went through this and grew out of it when she was 4.5 - has never had an accident since.)

Totally understandable that she'd start to show some apprehension, kindergarten can be scary. Will you be able to visit the school to tour before she starts? Ask any teachers or office workers if there's a sign up sheet with contact info. A few moms in my daughter's class reached out via email to set up play dates, so that the kids to get to know each other beforehand. makes a huge difference to have friends to look forward to seeing! Also, if you live in a town with bus service, find out whether they'd let her (perhaps with you) do a dry run for practice. Anything you can do to help her learn what to expect will help arm her with bravery.

There are lots of great books about kindergarten -- Timothy Goes To Kindergarten (almost any Rosemary Wells book), Miss Bindergarten Gets Ready for Kindergarten... Browse the library and see what you find. Ask her questions about what they say at preschool about kindergarten-- how does she think it will be different? The same? Does she think she has to know things that she doesn't yet? She may not be able to see clearly why she's freaked out, but with some discussions you may be able to figure it out, then help calm her fears.

"The Kissing Hand" is a great book and is a classic. I really recommend it.
You can find it probably anywhere... or online.
I got it for my daughter when she began Preschool.

Yes, regression like that, is a symptom of stress in a child, or that they cannot cope with something.

But keep in mind as well... that full night-time dryness, does not occur even until 7+ years old... and this is normal. Per our Pediatrician and many articles I've read. Being potty trained is different than night-time dryness. Because it is a biological thing as well. My daughter was 5...when SHE finally felt comfortable and able enough to just wear underwear at night. She is 7 now... but once in a blue moon, she may have an accident.

At this age, many kids do take time to adjust. Its normal for such a young age. My daughter was like that.

All the best,
Susan

Have you tried a potty pager??

There is a great children's book called The Kissing Hand. Can't recall the author, but it's about a little raccoon who is afraid to go to school and what his mother does to make him feel more comfortable. check it out. It's great!

My son (also 4 years old) has been potty trained for over a year now too...and has recently started wetting the bed at night. My sons doc thinks it may be a reaction to being nervous about the new baby coming (due in June) and he seems to think that is likely the cause of his reverting back to wetting the bed--he gets attention that way....So it could quite possibly be your daughters fear of change. My sons docs suggestion was just to ride it out, and that he should go back to normal after a period of adjustment to the situation.
