He had a very strong personality and she gave in far too often. Some of the stuff she gave in on was ridiculous.
If he didn’t want to walk, well she just put him in a stroller.
If he wanted to wear a superman costume to the mall in July, well she just let him. (No, this is not the worst thing on earth.)
If he wanted to suck on a soother, she kept a supply in her purse.
If he wanted candy for dinner, candy it is.
She took baths with him.
All this is fine when your kid is three. The kid was six. His school friends would see him in the mall, wearing a superman costume, in a stroller and sucking a soother.
Kids are already going to be bullied, don’t make it worse by allowing your kid to stay a baby. She was a dismal failure as a mother.
