Kids in school with earlier birthdays do better in school than those with late birthdays. I agree I was often the youngest born in December literally teased for that,took speech therapy special education classes and etc. Mom and Dad need to think when they screw about the kids future. Do it between late April to mid August is the best time it will lead to an early birthday January,February,March,April possibly May leading that son or daughter to be the oldest or one of the oldest in class. Conceive Sept -Nov will lead to a mid birthday June,July and August which aint bad in between the oldest and youngest of peers. Conceive from Dec to March leads to a late birthday September,October,November and December. If I had a son or daughter I would be very happy if they were born in January,very happy February,very happy March,quite happy April,happy May,ok not bad June,ok not bad July,ok August,September,October and November not thrilled and December certainly not thrilled. My moms parents conceived the right time she was born January 11th oldest of peers,my dads parents conceived right time he was born April 23rd. Valerie my old friend and pen pal parents conceived right time February 23rd she was born.My parents conceived wrong time and I have suffered the consequences for it. I am dead serious on this matter,I have wanted to be dead,because death erases birth solely due to me having a late birthday December 9th not the only reason,but one reason.
