I'm a mother of ten children here in Eau Claire, WI...not that far from you. I've had children 1.5 to about 3 years a part....most of them 2 yrs. apart. Believe me, I'd prefer the 3 years apart gap. It gives me time to loose weight...get in shape in between...that one on one time for a couple of years with the current baby, etc.
I never had any complications...had mostly home births that went just fine...even with one being breach...he came out fine and is a healthy 14 year old now.
After having had 10 over 22 years (they are now 25 down to 4), I would recommend whatever amount of children you have....have them so they are at least teenagers by the time you turn 45 to 50...it's no fun combining raising little ones with menopause, etc. Believe me, I know. But I'm glad I have them all....grace & thankfulness is needed every day.
I don't know if you're a Bible believer, but I sure clung to scriptures like... "Shall I bring it to the birth and not cause it to come forth?" Isaiah 66:9 Only had my first child induced for the doctor's scheduling purposes. After that they all came in due time just fine naturally.
Also, I like Psalm 127 esp. vs. 3 "Lo, children are an heritage of the Lord: and the fruit of the womb is His reward." So true.
Hope this helps. Glad to help...hopefully.
