Dang, commenters are harsh. I mean, don’t get me wrong, she’s a pretty bad mother, and I’m not excusing her behavior, but she really wasn’t prepared to be a parent. It’s a lot to ask to give up much of your life to raise a child, especially so when one becomes a mother as young as she did. It’s not uncommon for young/teen mothers to resent their child, even while they love them, because they feel like they were robbed of their freedom as a youth. Having a child at a young age forces a person to grow up a lot faster than they should (not unlike war or trauma in that aspect). She definitely needs to put in the work to do right by her son (though I’m not sure if she even knows how to be a mother given how young she was when she gave birth), but as far as bad mothers go in manga/manwa, she’s one of the tamer examples as far as I can see. She’s more neglectful than abusive (still not an excuse, and definitely something she needs to correct) but it’s not like she’s beyond redemption.
