Am I wrong? Need advice

So my husband and I have these neighbors. They have tried to build a friendship with us and we somewhat have with them. The issue is our little girl will be born in March.

These people are nice, have done nice things for us. However, they aren't the greatest influences. The guy is really nice and has done alot for us and we enjoy his company more, the woman can be nice but she only comes around when she wants something from us.

She is pushy at times and when we don't answer her messages or calls right away she literally blows up our phones or has other neighbors let her up to our door. They live in complete filth and don't probably care for their children. This bothers me. They have tried to include my husband and I in their relationship issues many times (abuse) and won't follow any advice we give them. This woman allows her toddler to rip off their diaper, tear things up, and once he drank his own pee from his own diaper, and he peed on the floor. She has the kids in the same clothes for days, doesn't dress them for cold weather properly at all, and they are constantly sick. New born and a 2 year old. Her toddler can't even speak, eats off the floor(she puts their food on the floor) and/or use the potty chair.

These are some of the issues going on and we don't want to hardly be around them let alone take our child around them. One time this woman used her toddlers dirty t-shirt and placed it on a pan(baking sheet) and put fried fish on it out of a dirty pan she cooked it in and served it to me. Her husband says awful things about her behind her back and says he hates her, she's a gold digger, etc, one minute then acts like he is crazy about her and wants more kids. Half the time he ignores her and the kids and we have suspensions he has been unfaithful. All in all, people aren't perfect but are we wrong for feeling uncomfortable with continuing to be around them or not wanting our child around them?
