Buy a waterproof mattress protector oh well if the sheets gotta be washed
My son wakes up dry but we still do pull ups at night. For this reason, I don’t want to clean the sheets. I’ll probably take it away when my pulls up run out in a few months. My son is 3.5 too for reference!
We do pull ups for now but he’s been night training himself and waking up to use the potty during the night.
Mines 3 and he sleeps in underwear. If your afraid of an accident deff make him going potty as part of a night time routine too. We bought a waterproof mattress protector!
Underwear for about 6 months now. He was staying dry through the night for around a month prior to us switching from pull ups to underwear
We switched to "underwear " when my little was 2.5 yeard old. My daughter has really sensitive skin so she actually skeeps in pj's without underwear so her skin can breathe. But we did buy reusable absorbant cloth pads that we put under the sheets. Can't recommend enough as her waking up vomiting (daycare bugs) has saved us from washing all the way down to the mattress protector. We do have an extra set of sheets for her bed for in thr middle of the night accidents. I would say about once every 3-6 months she may have a pee accident, but it typically follows an illness. Good luck!
Underwear here! We were nervous at first, but have had 0 nighttime accidents. I’ve also seen people put multiple layers of absorbent liners and sheets on the kids bed so if an accident does happen you can just toss the top layer and there are clean ones underneath.
