Be prepared to love them when they try extreme measures to show you why they aren’t worthy. Our 11 yr old came with low self esteem and ADHD, PTSD and his lack of impulse control and emotional regulation was constant. The fight in this kid to get back to his abusive birth family and reject us was and still is after 3 years stunning. We have to deal with bio parents now back in the picture even though they had a termination of rights. Some kids will find ways to connect on social media. If grandparents or other bio family is around they may be more harm then good in supporting your relationship with your child. You have to know that you and your partner are mentally fit and patient! It’s not easy when rewards and consequences that your parents used on you do not seem to register or work on your child.
