Your right Ironoaks, It is a big thing starting uni. More independent learning, moving out of home, having to make friends, looking after yourselve more ie washing and cooking and cleaning. During the lockdown I face time DD 3 times a week, just to make sure shes ok.
@HuaShan glad your DC is settled and happy :) maths is pretty full on. DD does physics and particle physics, so her first years, half of it is maths based, so vectors and calculus matrices etc. lucky hes not in self isolation though, quite a few have DC on mumsnet that have. DD just counting the last 4 days till freedom.
