Holly uses both. If I take her out every 3-4 hours she goes outside...if not she uses pee-pee pads. The pee-pee pads are also kept in her play area when we are at work since she cant hold it in for 8 hours. Do what is best for your baby and dont be discourage by what other people say
. I use both and Holly isnt confused or etc. She knows to use both and does.
