I find that we are not following the weight requirements on the package
Right now LO is wearing size 4 pampers cruisers during the day and size 5 at night. She is nearly 12 months and I am about to start using size 5 full time once my box of size 4 runs out but she hasnt even reach the minimum weight for size
These are their weight guidelines for pampers cruisers

Size 3: 7 - 13 kg / 16 - 28 lbs
Size 4: 10 - 17 kg / 22 - 37 lbs
Size 5: 12 + kg / 27 + lbs
Size 6: 16 + kg / 35 + lbs
Size 7: 19 + kg / 41 + lbs

According to their guidelines we are using diapers that are way too big, but they fit her just fine. Are you using the "right size"
