Mulatto baby hair

Da
First time mom here, my partner is Trinadadian and I'm Ukrainian/Irish. I'm nervous to care for baby's hair and as they get older as I want to make sure it's natural and healthy and grows well. My partner knows nothing about caring for mulatto hair and so I really don't know where to start. I've watched a few videos but it all seems really intense. I know not to wash as often, maybe once a week and I was going to use coconut milk and acv to wash and coconut oil to moisturize but I'm not sure how to do hairstyles that will help with growth. Anyone else in the same boat or have some advice for me?
