She never says anything nice about her children. Poor kids. I don't know what it's like to have twins but she seems to be in a good age with them now, both potty trained and in preschool. She is not juggling a baby, a toddler and older children which most other people are doing that with zero help!
She doesn't have a job to go to in the morning, why doesn't she spend the next few weeks getting the children to sleep in their beds through the night, it would be short term pain but long term gain for her.
