It's driving me insane. LO is 18 months and today it's non stop whining. She is generally happy but is just walking/running around the house whining. We are trying to encourage her to point at what she wants and say please but just whines constantly instead. For example: she wants to read a book so she grabs one and brings it to us whining. We tell her 'no' and we will only read it once she asks nicely. She will say please but today it's CONSTANT reminding. So, how do you deal with it?
