I have an autumn born ds and we have noticed how much older he is than summer born peers. I'm an ex teacher so well aware of this anyway and have noticed the differences when children start school and how hard it it can be for them to move ability groups once they're set, despite best efforts. We are very aware that you can also do well if summer born. Dh and I both are and have done well in life , but we both felt like we struggled in some areas when young and really couldn't get certain concepts for ages e.g. one of us maths, one of us languages. We went to good schools and had tutoring so all fine in the end, but it is still interesting and notable to think about.
When we want to start ttc it'll be a May baby at the earliest then going all the way through the summer months. I feel like we would be giving our second a disadvantage to our first. Is this completely ridiculous? It would be different if we'd been trying for ages but would you deliberately hold off to at least try another autumn/winter baby? If our first child was also summer if might not feel so bad, but I feel like as a direct comparison we'd noticed how disadvantaged they'd be.
