I think perhaps a parent who had a very hard time finally getting a baby of their own. Wanting to keep them young, and infant like as long as possible, because they love it so much and know they won't be able to have another.
Also perhaps a parent who is very controlling, and wants to stay in control of their child. Knowing when they grow up, they will slowly lose some control.
Rational people always say,"I don't want them to grow up so fast, wish they could stay little forever!"
But irrational people actually try to keep them dependent upon them. Those are some of my thoughts on this subject.
