13 month old and newborn?

Hey ladies. I can’t sleep right now. I am 36+6. I have a son that is now 13 months. I don’t live near any family nor friends. Every since I gave birth to him, he’s only seen my family about 4 times total. He’s always just been with me and his dad. I breastfeed him so that’s the only milk he will take. He won’t take cows milk, almond milk, or oat milk. Anyways, I’m so worried about when I go into labor. His dad had asked the hospital if we can take him with us when I deliver because we don’t have anyone to watch him but they said no. So I had asked my dad to watch him and he said yes but he’s always been scared of my dad. I’m not sure how my dad will even handle it. I’m stressing so much. :(
