In a short answer no.
Turn your nappies inside out, have a look at the PUL and see if the plastic has come away from the coloured fabric. If it has then the nappy has delaminted and past its use by date.
If it hasn't and the PUL looks fine then you probably need to do a strip wash/soak on your inserts and add more absorbancy to your nappies as your child is probably doing a big pee and the inserts cant handle it cause they are bunged up with other stuff. Rockin Green is the way to go, you can get sample packs from Tweedle and Mothers instinct. Soak overnight in a bucket then do a normal wash with no powder and they will be like new again.
I hope this helps, let us know how you get on
