Whatever nappy! It totally depends on your babies bottom and tummy shape and size and how you do them up!
Eg, my LO (well BIG ONE) is in size 5s and has been since 8mths. Pampers and Boots are too tight around the tummy, Asdas were too loose so we got leaks. Huggies fit perfectly so i dont get the UTI infection smell from Pampers!
Pampers are great as they are soft like cotton and dont "bulk" the bottom but they are so full of chemicals (to get that look even when full) they fecking stink.
No one brand is the best. It all boils down to your baby's bot'!
Also, some people may strap them too loose. My pal was told by the midwife to not make them too tight. Every time her LO lay down she would get soaked because the nappy was too loose and the MW' advise was taken to literally.
