Congratulations on becoming a father.
You're family can't do that to you. If you think you're a capable parent, chances are you're right, and any welfare people would see that. If you have a partner of any kind, they should also be able to back you up. Nobody's a perfect parent, but just because we're Aspie doesn't mean we'd be any worse than NTs, and a lot of us are probably better.
Sometimes families get things wrong. Ignore them.
