It was so simple; all Felicity had to do was treat Phillip as a baby, and eventually a baby he would become.
There were no magic tapes, no threats of physical punishment; she just had to be a Mummy for him.
It hadn’t taken long, just a few months, and that was it, his adult life had gone for good, he would now only ever be a baby. Not only did Phillip look like a baby, but he behaved as a baby. Felicity was so happy she had chosen Phillip; she could not have wished for a better baby, he answered all her maternal desires.
For Felicity it was the best relationship she could have wished for, she was the one in control, Phillip had no say in the matter at all, he was just a baby now and would remain a baby.
