Hi mamab30
I remember feeling a bit lost both when DD1 and DD2 traipsed off to school - and yes you are entrusting the school to educate your children. But it isn't just 'book learning' - going to school is about learning to follow instructions, learning to work well with others, learning to be part of something (a group, a team, a house, etc...). Learning to navigate a situation outside the home which ultimately after years and years in education is meant to prepare you for being a responsible adult, a good citizen and for the world of work.
I understand the feeling of loss of control. Many have posted here about wishing their school would or wouldn't teach things. I have had some pretty serious doubts myself about what is taught/ how things are taught at our DDs school and where the emphasis is placed. There are teachers and teaching assistants I've had some serious reservations about and there are teachers and teaching assistants who I think are worth their weight in gold.
The point is your DS is starting to learn about life outside his home with the safety net of coming home to you and I'm certain he's coming to a home where he's loved and supported.
Class R and Key Stage 1 are a difficult transition for us Mums and Dads who are used to being the centre of their universe. It can also be a very tiring timefor children - but I assure you that they will adjust and be brighter in the evenings. Right now Class R may just be too full on - but I suspect with the coming of Spring your DS will have more resilience for these busy school days.
We parents have to realise that we aren't the source of all knowledge, our values may not ultimately be theirs, our priorities may ultimately not be theirs. Our job is to be there - to wait during their swimming (or whatever) lesson and clap when they do well. To attend assemblies and plays, performances and sporting events, to always show pride and look on the bright side. To tell them never mind when they've had a bad day at school, haven't done well on a test, etc... Our job is to instill in them an appreciation for those things we value - and the list will be different for everybody.
It is a difficult transition mamab30 - but the reality is that children grow up and we parents and schools/ clubs/ lessons/ and practically any inspiring experience will influence them to ultimately become productive young men and women. Every parent hopes their child will reach their full potential - but I think we all know that chance is also a factor - that inspirational teacher or experience, the opportunity to meet an expert, the wonderful documentary/ lecture shown on tv, access to museums/ galleries, opportunities to travel, etc...
I've found my role has become a mixture of chaffeur, short-order chef, homework tutor, 11+ tutor, sports therapist, on-call doctor and occassionally (just occassionally these days sadly) cuddly Mum. My solution to feeling included is to be there and use those car drives/ waiting moments/ dinner times as an opportunity to discuss how things are going, what they're currently enjoying, what they do and don't like and to be enthusiastic about this whole wonderful process of learning.
It's brilliant to be an involved parent - but it is also important that you start to build interests and activities of your own. Our children will grow up and fly the nest, it's natural. So we must understand that ultimately we are raising them to go on and have a life of their own.
