Thanks all!
Thanks to every body who replied, it's been very helpful managed to speak to Monarch who were able to tell me which aircraft it was and checked the layout and managed to work some magic.
So additional thanks to all who PM'd as well - I'm very grateful.
Upshot is we're close enough now and on the aisle so it does make things much easier.
Seja...you're quite right, we got into parenthood quite late 2 at a time! In fairness the Mrs is totally laid back about it and was planning on bringing some popcorn and watching me sweat for the duration! The boys are very laid back just like mum so I'm sure it will be fine
It's the adjacent pax I feel sorry for!
Thanks again everybody
