Should I put DS back into nappies at night?

[2point4kids]

He is nearly 3 and been out of nappies for 3 months.
Stopped the night time nappies too about 2 months ago as he didnt want to wear them any more and had gone from being wet every morning to being mostly dry.

2 months on and we are still having an accident about once a week on average. Usually when he is deeply asleep so cant be helped.
Have had a wet bed for the last 3 nights in a row.

Am thinking about putting him back in nappies at night. Is this a good idea or bad idea?

his still young so may not be ready to go without yet

i would say put in nappies my ds is 3.3 and still in nappies at night i have just bought some waterproof training pants off mothercare website to see what they will be like hopefully they will hold and then its pants not a nappy going on

He's obviously not ready yet, so if it were me, I'd definately put him back in nappies.
