Advice

So I’m 34 with a 10yo son and another boy on the way. My boys do not have the same father. The new baby’s dad is... how do I say, a bit uneducated? He seems to think raising a baby is a walk in the park. His friends all have kids and they have even told him “it’s not as easy as you think”. He is adamant on thinking otherwise. He doesn’t understand the concept of some things when it comes to baby’s safety and health. For example, I mentioned SIDS to him the other night and he had NO IDEA what that was or had even heard of such a thing. I love him and he is so very good to my son, who is not his, but I’m so afraid to leave the new baby alone with him after he’s born. I’ve bought baby books for him to read and he states “I ain’t readin that shit! I don’t need someone telling me how to raise my kid!” It’s so frustrating. I’m trying to be patient and not just completely loose my mind on him but this is a BABY!!! OUR CHILD!!!! He likes to use the phrase “no one in the old days had to raise kids like this! They use to just wing it and didn’t have all this filtered water non sense! It’s water! Any water will be fine!” Now I can agree we don’t need all the high tech savvy, unnecessary type things but I do want the absolute best for this baby. Any advice on how to handle this or how to approach this in a different manner?
