As close to 40 is the best. However, there are many babies that come at 37 weeks and are fine and ready to go home. I was born at 37weeks exactly and was a healthy 6 lbs 8 oz. Though mom says she swears I was bigger than that XD But I know what you are saying. I personally don't want to give birth before 38 weeks and am paranoid that I will have another large baby and my doctor will try to induce early since he doesn't want me to have another large baby like Claire was. He said we'll talk more on the matter if it comes to that. Who knows maybe this little one will only be a 7 lb baby.
I still can't believe 35 1/2 weeks for you Barb. I really can't. I know you're going to get at least the 37 but I personally think baby boy wont come until 39w 2d that is what I feel for you. Don't take my word though I don't have the best track record on when baby is going to come. Though I was right with Claire X'D I often had told DH and family that she will come one day early. So maybe I should look into predicting actual dates X'D
What is your body saying?
Also I agree what Orchid just said. Be open to everything.
