The reason why you should choose Pampers over Huggies is because Pampers are more superior and lock away moisture and maintain dryness much better than Huggies diapers.
Pampers also tend to fit better than Huggies diapers and can be cheaper as well.
Pampers are also better for babies and toddlers with longer and slimmer built bodies.
Although if your baby or toddler is on the chunkier side then the Huggies can be better due to the stretchy straps.
Huggies are still pretty good diapers and work for many babies and toddlers although for some Pampers diapers is much better.
Pampers diapers are also used by many hospitals and are recommended by pediatricians as Pampers has superior leakage protection and also safe ingredient choices.
And all Pampers diapers are also free of any latex and parabens and are hypoallergenic and ensures that your child is healthy and safe.
Although Pampers and especially Pampers baby dry are scented which some parents may not like and some babies and toddlers or children may be sensitive to the scents in Pampers and if so then Huggies would be a better option.
I've used Pampers Baby dry on my kids and had no issues and even Pampers Cruisers tape on diapers are also some of the best Pampers diapers, especially when your toddler gets active and moves around a lot.
