I’ve tried for two years with these kids (2 SD) and nothing works or has changed. They are the rudest and nastiest children I have ever met. Zero manners, zero respect - the youngest of the two purposely would try to kick my stomach hard while I was pregnant. She thought it was hilarious.  I have bruises on my body from where they have kicked me and bite me. I can’t do this anymore. My anxiety goes through the roof when I know they are coming to visit. I try so hard to do nice activities and provide nice things for them - but they always ruin it. Every single time.
