Am I wrong?

Am I horrible for wanting to look for work after I have the baby? For where I am financially it would be in the best. However the only people that would be able to watch the baby unless I only work on my boyfriends day off is my boyfriends sister, who smokes weed in her house in the living room while her child is there. She puts him in his room closes the door and smokes in the living room, then there’s my best friend who just had her own baby. And although I know she CAN care for baby, I’m just not sure if my child will be her main focus? It’s only natural to have your child as your main focus and although it might not seem as hard with one infant, 2 infants by yourself will definitely be a challenge and she keeps offering but I just don’t think I could trust her to watch and care for my child like she would her own? Am I wrong to think this way? Or am I just paranoid?
