Argh, DS's wandering hands are causing night-time nappy leaks...fed up of laundry!

[Poppet45]

As title really, DS 2.5 has, to his delight, discovered his bits, so every morning we find a soaking wet boy in a wet cot, with wet PJs and his nappy looking seriously 'tampered with' as he's obviously had his hands down there. He's still in a poppered up vest but it doesnt appear to help. Just fed up of laundry really and wondered if anyone had any suggestions... will post in nappies too but figured sleep would be busier.

Can you still get all in one sleep suits? If so put it on back to front!

Sleeping bag? The grobags are harder for them to undo.

What about a cloth nappy with a PUL wrap with poppers (Mother ease are good). You would have to wash the cloth nappy but even one every night could just go into the next wash and the wrap would only need to be washed ever couple of days. So lesss washing then pj sheets ect
