Pampers nappies burst all the time

My baby wears size 4 pampers nappies. I have purchased several different packs in different quantities but have found the same problem with all of them: the nappies continuously burst leaking urine filled gel into my baby's clothes, cot and/or play area. <br> This is a recurring problem, not just something that has happened once. I have photographic evidence of several of the occurrences as proof. I find this very disappointing and actually quite dangerous as babies tend to pick up anything and everything and put it in their mouths. We change our baby's nappy regularly and have had nappies burst like this even when they are not full. <br> In addition, I find that soiled nappies leak about 70% of the time even though we use sufficient barrier cream and change soiled nappies timeously. <br> Several nappies within a pack are also lacking elastic in one or both sides meaning that they do not hug the buttock but rather flap openly and have to be discarded and replaced with a new nappy. I'm very unhappy with this product.
