It's a shame to say, but until this time, my mom-in-law had been making Ha-min's meal instead of me since I was not confident in cooking at all (especially, for a baby..)

“Mom-in-law” isn’t in usage so far as I know. “Mother-in-law” is the accepted expression.

I think “before she said so” is implied in “before” here, so no need to spell it out.

It took hours making it and fortunately, Ha-min ate it wellenjoyed it. It took hours making it and fortunately, Ha-min enjoyed it.

“Ate it well” isn’t an expression. I wasn’t sure quite what you meant, but I’m guessing “enjoyed it” comes close.
