I really like this.
Children always depend on the parents so much, but sometimes parents don't return the favor.
It's good to see someone use this idea in a poem.
There are a lot of layers to this, every time I read it there is a new aspect.
The perspective you have chosen is very good, it allows you to observe the situation, It would have been sappy if it was by the child who adores him or the mother.
The lines are a bit choppy, try and straighten them out.
There are a couple of punctuation errors
I don't really like putting things in brackets in poetry
Just some constructive criticism.
