My Little girls nappies keeps bursting open

I have two little girls 1 is 5 years and the other 16 months. since day 1 i have been using huggies gold for both my babies,i encountered a few problems in the past with my first born using huggies the velcro straps kept falling off i was asked to give the batch number and i was rewarded with a voucher to replace the pack I was very pleased and i didn't come across another problem.My second daughter also used huggies from day 1 and i continued to use huggies gold until i saw \huggies for girls"its a great fit and i love the Minnie mouse detailing on the nappy it also makes it much more inviting for my little one to change a nappy without any hassles as she is fascinated with the bow on the back"
