Would you allow people like this around your baby?

I had a baby in May and since then, I have greatly distanced from my dad and his side of the family. I believe he is a narcissist and he’s an alcoholic, my grandma vapes, drinks, smokes weed, and has a pill addiction, my grandpa enables her and can be a complete dick. On top of it, they used to treat my SO and I like shit and talk about us when they thought I wasn’t around - up until I announced my pregnancy. THEN it was “we’re so excited” and they had all these plans to super pro active in his life.

Since my son has been born, I can tell my dad tries to act like this is really his baby, pushes boundaries, will take him out of my arms if I’m holding him and he wants him, says he would kill animals to protect him, wants to be in his face every second possible, etc. Basically obsessed. It got creepy to me so I backed away quickly.

ALSO since he’s been born, my grandma has been hospitalized multiple times, and was even put in a coma, for injuries related to such heavy drug usage. The coma was in July. She insisted to meet my son for weeks before and then continued basically as SOON as she got out of the hospital and I didn’t want to. She also continued drug usage. But my dad pressured me and I got tired of fighting so much that I tried to compromise. I said “if she’s sober and will not drink/vape around him, sure”. They got offended and said that because I made the request, they don’t want to meet him. This raised instant, HUGE red flags for me and I have not given them another chance to meet him since.

With Christmas coming, some of my family has been making comments like “will I EVER let him meet them?” “There was drama but you should give them a chance”. between their pattern of disrespect, their reaction to my SIMPLE request, the weird attachment they all have to my baby (grandparents also have bought mountains of clothes to bribe us to visit, demand to meet him before a certain day, show jealousy towards my SO’s family simply because they are baby’s family too, etc.), and the substance abuse makes me feel uncomfortable giving them a chance.
