My four year old is complaining ...

Mandy • I am 34 pregnant w my second. A baby boy. My daughter, who is 4, was born a preemie and thus I'm a NICU Mom.
I just need a little hell here mamas. My 4 year old daughter has been complaining her but hurts for the last two days. Today I put some diaper rash cream on it. She didn't mind. Am I on the right track?
