So my husband and I just had our little one August 23rd 2011. We are trying to decide when would be the best time and how far apart our children should be because we don't like the 5 year difference between him and his step brother (my husband's son). At first we were looking into having another in 2 to 3 years. Well that would put me at 30. Well I heard pregnancy is harder when you are 30 or old…
