Very Disappointed

I'm very disappointed in nappies . I have been using this brand since my daughter was 3 months old and she's almost 2 years old . This is my first time having this problem. She has the nappy on for an hour or 2 then she's soaking wet. The wee dripping down her legs. I buy 2 packs of size 4+ for the month . The 1st pack was fine but the 2nd pack is just a waste of money.
