Newborn advice

Hi. My son is due in Oct by surrogacy. We had many failed IVF egg retrievals and finally got an egg donor and surrogate. I’m very grateful to be a mom and kiss his cutie pie cheeks. But I can’t say i’m not anxious about less free time, more to do and NO SLEEP. I have very bad chronic migraine which is somewhat managed now. Lack of sleep will not help me medically, let alone in any other way. I totally know this is part of the deal. However, any tips? I’m nervous. Ty in advance.
