PoseyParker, you'd have totally hated me then! I got full funding from a British university to do my PhD. What do you know? Three years of fees + monthly maintenence for three years. Plus, I got the international fee difference paid for by the Overseas Research Student scheme. So, I did this PhD, and, thanks to dear husband's work permit, got naturalised as a British citizen... and do you know what we did next? We left to go to Canada cause DH got a good job there! My husband paid his taxes in the UK though, just in case you think we're scamming immigrants. Nah, that's true, I probably was a scamming immigrant, despite over 5 years of working my arse off afterwards. Boy, you must be steaming by now eh?
And you know why I got all this support? Because I was fucking brilliant at my studies all my life and my research was considered worthy of being supported internationally.
Secondcity... here is an experience for you. When DD was 18 months, we went to Canada for a visit to the GPS. I had to go back to the UK early, because of work. I was pretty sure I couldn't leave DD behind, was quite stressed and all. And a funny thing happened when I went back to the UK. I 'talked' to DD practically every day using Skype, and telephone calls. And in three weeks we saw each other again. What do you know? She was super pleased to see me, but she hadn't missed me at all. We have a brilliant relationship.
I love my parents and sister, and talk to them every day using Skype. They happen to be in India.
The point being - yes, your children will miss you. And oh yes, you will miss your children incredibly. But we are very lucky to live in a world which is very close, both technologically and physically. The academic year is not that long, and time flies incredibly fast. Between your studies, talking to children, and co-ordinating visits, the time will just disappear.
And to show for it, your children will have a mum who was no afraid of 'what people would say', and grasped her chance at doing what she wants to do.
Fully funded MA courses are very rare, and you are incredibly lucky to get one. Its highly unlikely that you will get this opportunity again, given the future state of university finances. PLEASE PLEASE take it. Your whole family will be happy and you will be much more fulfilled if you take your opportunity.
It's really should be about working out how you're going to work all the usual logistics of going away now, not about whether you should take the course up.
And before anyone asks, if I had this opportunity and my child was the age of the OPs children I would totally take it and be grateful for it. It doesn't make me selfish. My DD has an incredible father who is also able to look after her equally well.
PS - Sorry for the essay, but some of the comments made me so mad
