DS (2.4yo) is potty training during the day but not at night. He is an heavy wetter at night time.
I have tried Huggies Pullups at night but they leaks, so last time I put him in Pampers and had the lovely surprise this morning to find that he had removed the said Pampers and pooed in his pjs.
DH is suggesting cable ties to hold the nappies 
Any suggestion on what to do?
