Pretty much that. (Sorry a bit long, but wanted to set it all out rather than drip feed.)
My DDs will be just 4 and 2.5 at the time. He wants to go to visit family in South Africa (we're both from there) before DD1 starts school and we are "tied down". But I won't be able to get more than about 3 weeks leave max.
He plans to get his mum to help a bit with looking after the girls and also wants to put them into nursery for mornings only because he'd like to be able to go see friends, go surfing etc while there. And it's unfair to ask his parents to look after them all the time if he's not around. I've said that I have to be 100% happy with the nursery (they are less regulated there, plus his parents live in an area where few people speak English so I want to be quite sure it is truly dual medium at least as my girls don't speak any other language) and DH is fine with that.
DD2 has never been to nursery (she's at home with our nanny when I'm at work) and I hate the idea of her settling into a nursery in a strange country, with strange people fetching/dropping her sometimes (they are her grandparents but she doesn't see them often so they are effectively strangers to her) and with no mum. She's quite clingy and she's always been looked after by me or our nanny and never had to deal with the rough and tumble of a nursery.
DD1 is at nursery now (she's 3 so gets the funded place) at our local primary school. I hate the idea of her missing out on nearly a term there - even though logically it doesn't mean that much long term. And I worry about her settling into a new nursery in a strange place. Just because she's fine here doesn't mean she'll be fine there. She has just started at the primary school nursery (was at a different one last term) and has been not quite herself the past two weeks - a bit tearful, a bit tired, wanting mummy quite a bit. So I worry about her too.
And I just plain hate the idea of my girls being away from me for so long. I'm probably just being a bit selfish here but they are my girls. And I'll miss them like mad. And stupidly I just feel no one looks after them quite as well as me. I know that's dumb - DH is their father and my MIL had 3 children herself so knows all about children - but at the bottom of it that's how I feel.
I can't say DH can't go. I can say that the girls go for less time - but that does mean part of the reason for going (that they spend a lot of time with family before school terms prevent that) is lost. And basically only lost because of my selfishness/worries.
AIBU? Is there a middle road I have missed?
