I think the pressure these days on kids to go straight to uni is immense.
My DD is 18, finished a Business BTEC this summer, but really has no idea what she wants to do for a career and is also quite young for her age. She has taken a gap year, but in reality this is likely to turn into two years. She has a retail job, with plenty of overtime, and is having an induction for a volunteering role in the caring sector this week. She is also a young guide leader, about to start official training for that. She plans to work till next summer (both to save up and wanting to attend an event that only happens every few years) then go abroad for volunteering/travelling.
We are happy with her plans, she helps in the house and with dog walking, and is becoming more mature and independant by the day.
But we have a number of friends who see A levels then uni at 18 as THE only route, and have made it clear through their comments that they look down on my DD, both for doing a BTEC and for not being at uni. They cannot understand why I am not pushing her to make a career choice now, like they are with theirs.
One friend, whose DC have never worked a day in their 20/17 yrs, openly told me that she thinks retail work, as my DD does, and DS has done in the past, is the absolute pits (and seemingly below her DC 'who wouldn't want to do that'. They don't seem to want to do any work). I avoid her as much as possible now.
Another, with a DD in yr 13, is adamant that she can only have a gap year if she has applied for uni this year, despite admitting that the DD is not sure of what her chosen course entails and is struggling to write her PS! My suggestion of letting her apply with actual grades next year was knocked back. Not having a place this year is just not an option in my friends mind. She actually said to me this week, that her DH wondered where they had gone wrong in bringing their DD up. I was speechless.
Op - my DS went to uni at 18 two years ago, and was the only one in his house share last year that was 19 turning 20. All the others were older than him, some by a year, some by 2 or more. DS has always been quite mature, but it was interesting that the eldest of the group very much led the way in getting the house, liaising with lettings agents etc.
Let your DD have a gap year, to find her feet a little, without being forced to go down a particular route now.
