Bismillahi Rahmani Rahim
Salaam Alaikum wa Rahmatullah
May Allah bless you with a good labor and delivery and a healthy baby, Ameen.
I am a little bit behind you - I'm due in mid-June. This is my fourth, so I've been through it all before. I have always kept my hijab on when in the hospital. Try to make sure you have one that's easy to wear, some light knit pull-on scarf that you can put on and forget about. I find it actually is helpful because my hair is neatly in place and not falling in my eyes or bothering me.
Since this is your first baby, labor may take a while and you might have a lot of men coming in and out - nurses, techs putting in IV's or drawing blood, service people cleaning up - so you do want to stay covered as much as possible. Wear something you won't mind tossing after you leave in case it gets messed up, lol. Babies are very messy when they are born!
Let everyone know that you are Muslim and that men, from doctors on down, should KNOCK AND WAIT before entering so you can cover (like toss the blanket over you) before they come in. Have them put a sign to this effect on the door. If there is a patient advocate in the hospital ask to see her as soon as you are checking in to see that they respect your wishes. And if a man does accidentally see something he's not supposed to, just say "astaghfirullah" and don't dwell on it. Do the best you can and concentrate on having that baby!
I don't know any particular du'as in Arabic - I keep it simple, la ilaha il Allah and such.
My sons were circumcised in the hospital as well. It's not that important to wait for a particular day. Some cultures wait until the boy is 7 YEARS old, ouch!
Breastfeeding is so important. The best thing you can do is to make sure you stay hydrated - drink lots of water in the hospital and eat well. When home, continue to drink a lot and take your vitamins. The baby will seem to want to nurse 24/7 the first week and that's normal - he won't be getting milk the first few days. Initially your body produces colostrum, which is rich in antibodies and vital to getting him off to a good start. Do NOT let the hospital "supplement" with formula unless there is a valid medical reason to do so. The baby nursing a lot is NOT a reason, lol. Most babies lose weight in the first week, nursing babies a bit more because mom's milk doesn't come in right away. Once again, normal, so don't let anyone tell you your baby is starving if he loses a few ounces. You'll be taking the baby in for first examination so the doctor will make sure the weight loss is not excessive and there are no issues.
Most importantly, relax. If you are tense, your let-down reflex will be impaired and your milk won't be there for the baby right away. Find a nice quiet place, ignore any dirty dishes and such at home, and concentrate on getting to know your son. It is a beautiful way of bonding and once you both get the hang of it you'll be so happy you are breastfeeding. If you have specific issues, the hospital probably has a woman who can help you.
Have to run but may Allah bless you.
