I always liked my birthday as a kid (earlyJune) even with exams. I liked that it was nicer weather, perfect distance from Christmas and actually being a bit younger made me feel less pressure to have done things by a certain age. As an adult though, unless I'm abroad I find June a bit of a disappointing month, especially as the weather tends to go through a rubbish point after May. I'm now a real autumn lover, especially as you know what you're getting! I also look back and think how much harder I found school in primary. I caught up and had great teaching but I know a lot of summer babies dont. It also affected my self esteem in certain subjects.
I think about it more having dc. My baby was born in November and I really like the fact he will be older in the school year, although hope he doesnt find his Birthday too rubbish being near christmas! Hoping to always try and make it special.
