Leaking strapless nappies

Leaking strapless nappies. I bought two cuddlers size 4 nappies at shop rite, total waste. My child used one pack in a week. One nappy lasts two hours or less. The straps are tearing off and he is always wet. Never again will I buy this brand. Money is tight. I spent R159 for each pack. Big mistake . I regret this.
