My blood is boiling right now. SO just met BM's mom to give her the kids for the weekend and the reject showed up with a booster seat for SS4 who weighs 32lbs. In our state, booster seats are illegal for kids under 40lbs. She didn't even have the f*cking thing strapped in right!
SS3 (36lbs - yes he's our eater) was put into the right kind of seat, but she strapped the seat in by putting the lap belt across his lap and nothing else.
...and people wonder why I hate when they get the kids. She giggled about it and said, "oh, I've never put their seats in before" which is a total LIE. The last two times BM wanted the kids for a weekend, she sent her mom to get them and she put their seats in at that point as well... UGH! I wish these morons would do the kids a favor and step out of their lives already.
