So DD3 is 5 in march

so i had the choice of starting her in march where she will be in reception/prep for only 3 terms then head up to year one or holding her back a term and starting halfway through the year but meaning she wont go up to year 1 the following year and will still do a full year of prep/reception, as minimum is 3 terms maximum is 6 terms of prep. We chose option 2 so DD wont be starting school til term 3 and will do 6 full terms of prep/reception.


We chose this because DD is very clingy, emotional youngest child who still sometimes gets upset at day care drops offs but is slowly gaining confidence. the big factor for me to hold her back is I am due for a baby exactly when she would be starting full time school in term 2 if I send her so I worry that with new baby arriving and her emotional issues as well she may see it mummy sending her off cause the baby is here... I have talked to her about school and she couldnt care less if she goes or not, much prefer to stay home with mum (hence the huge worry of sending her right when new baby arrives) arghh just wish SA did the once a year entry starting this year rather then next because then she would be starting school in two weeks and the baby wouldnt be a issue.

but now with school starting soon I am beginning to doubt my decision. DD will be older then some of the kids in the grade above her plus SA has decided to come in line with all other states by doing the one entry a year so the first year she does a full year of reception the kids who will be in her class will be up to and just over a year younger then her. So this cause cause issues down the track, she will more then likely go through or start puberty before her friends, will get her drivers license before then etc but I am also worried about the teasing? whether they will give her a hard time because they assume she has been held back?
Do you think the age difference between her and her friends could be a huge issue?
