I am planning to start potty training DD - she is 2yr 2.5 mo. I don't want to nap or night train at this point. I bought pull ups for nap & night. Her twin brother will still be in diapers. Is it weird to put one kid in a night diaper & the other in a pull up? Am I over estimating how absobant pull ups are (she wakes up will a full night diaper still)?
