Excellent pampers
Size: Size 6, Unit Count: 50
Something I really like is that they absorb very well and help prevent leaks, even overnight. The material is soft on the baby’s skin and so far has not caused any irritation. In addition, the adhesive tabs are strong and allow for an easy adjustment, helping the diaper stay in place even when the baby moves a lot.

Best for a blow out!
Size: Size 5, Unit Count: 58
We loved pampers for months then my baby turned 7 months and started having blow outs bc he was so mobile. Huggies little movers fix that problem! Nice and thick, completely leak proof by the legs and up the back, nice and soft!

Great diapers, just a couple small issues
Size: Size 4, Unit Count: 150
Size 4 have been super reliable for my baby. They fit well, don’t sag, and handle active movement without leaking. The absorbency is great for daytime and short naps. My only minor complaint is that they can be a bit pricey compared to other brands, and occasionally the tabs feel a little stiff. Still, otherwise it’s a dependable diaper that I would definitely recommend

Reliable Fit for Bigger ToddlersI’m
Size: Size 7, Unit Count: 88
These diapers are great quality and hold up really well for active toddlers. My son has always had thicker legs, and these have suited him really well without being too tight or causing irritation. He just turned two and is already in a size 7 (almost an 8), so sizing up has definitely been helpful for comfort and better coverage for US. The absorbency is consistent, and they stay in place—overall a very dependable choice.
