Potty training at night

Tanisha

My daughter is 4 and we’ve nailed the potty training throughout the day! But at night time she’s such a heavy sleeper she doesn’t realise she’s wet herself. We do wake her up like 3-4 hours between to go toilet and she does go but lately she’s been wetting the bed more than usual. Does anyone have any tips to help out because I’m running out of bedding 😂
