I had two c-sections--both emergency. The last thing I wanted was to have visitors at the hospital. I was exhausted, experiencing some pain, trying to figure out nursing, and already had nurses, doctors, midwives, residents, and about 10 other people in and out of my room every half hour or so. Plus, my husband worked in the hospital so he had co-workers, who I didn't even know, sticking their heads in to say hi. I just wanted to be left alone with my baby!
Seriously, the best gift anyone could have given me was gift cards to restaurants. Especially to someplace that would deliver! Once my husband had to go back to work, there were nights when I barely ate anything. I didn't have the energy to cook or to pack up a baby and go out somewhere. Not to mention I couldn't drive. A second best gift would have been to have some home cooked meals dropped off for us. I would not have liked a housekeeper. I'm too private of a person. I don't get manicures or pedicures. I would not have been able to lay on my stomach for a massage. Any of those types of gift cards would have been wasted on me.
My suggestion would be to wait until mom has been home with the baby for a couple of weeks. Call or send a message asking if you can drop by and if there is anything that you could bring her. If nothing else, bring a gift card to Target or someplace like that.
I agree with what others have said about bringing gifts to the hospital. The rooms are so small and there is so much to haul home. I got a couple of floral arrangements that we left behind at the hospital because we didn't want to make multiple trips to the car. Especially since parking was two blocks away from the maternity ward.
Gifts for the baby--one outfit that is a 6 month or bigger size. Just make sure it will be season appropriate. Don't give a size 6 month winter outfit if the baby will be 6 months old in May. My favorite gift to give is books. Buy a couple of board books or cloth books. With first babies especially, moms get so many things. My first baby didn't wear half of the clothes she got just because we got soooo many.
It sounds like you really want to shower mom with special things, but honestly, it isn't necessary. One thoughtful gift is more than enough.
