The visit to the OB/GYN is a definite you can reassure your husband and get conceive vitamins too. I think your husband loves you and is afraid for you, himself, and your son. One spouse is always more practical and fearful of changes...sounds like he's just afraid of the unknown. I know you guys have talked about expanding your family..but it sounds like you have a major case of baby fever......are you sure he's not just agreeing to make you happy. Your first pregnancy was hard on you (of course you literally experienced all the good and bad) but your husband stood by unable to help eleviate your suffering, worrying that he had lost his young vibrant wife to a stroke....THEN he had to live through a dangerous delivery that endangered both his wife and unborn child...(plus he didn't get to feel the little guy grow and move)....hey your husband has been through the ringer...of course he is gun shy. Have you talked just about how the first pregnancy affected him? He may have to talk through everything you guys went through from his perspective to come to terms with jumping into the fire again. (Lets face it there is very little room for how Dad feels during the pregnancy and newborn phase....we as soon to be Mommies are very needy and self-centered...as we should be... and then it's all about the baby) Sounds like Dad needs reassurance from a doctor AND to deal with his suppressed feelings from pregnancy #1
I'm sure he'll come around.
Good luck and may you be blessed with as many beautiful healthy children as your hearts can love :)
