Terrible Lovies premium nappies

My son is a year and seven months old and I have used Lovies premium nappies for all three of my children and have never had a problem up until now. The nappies never stays dry and he has been urinating right through Lovies premium nappies. I have had to change is cot sheets everyday. I have had to put 4 to 5 outfits on him a day as well. I find this utter disappointing and a total disgrace for Lovies premium nappies to make such a cheap quality nappie.
