Here’s what the internet had to say.
“Your in-laws do not care about your nephew or his baby and gf. All they care about is that they don’t have to support them themselves. Stop taking their calls.”
“This is not your responsibility, you should not be the one who is taking care of and funding this baby.”
“It’s time to have an honest conversation; things become real once you bringing money into it.”
“Sit both kids down and start showing them how much it takes to raise a baby for the first year let alone the rest of 18 years.”
“Frankly if they are grown up enough to have a baby they are grown up enough to deal with the responsibility that comes with it.”
“Of course they can always consider adoption which will give them a lot more options and teenage freedom and wait until they are fully ready to support a child.”
“Otherwise, it’s time they get familiar with social services, WIC, etc… which can help a lot.
