I don't know, he's just so awkward about asking for any time off. I tell him about things with plenty of notice, but he aaaaalways leaves it til the last minute then wonders why he has problems getting it off?! So frustrating.
If my mum finds out he can't come, she'll pester me to come - I really can't be doing with that so I'd probably just end up going on my own (if you've seen my thread in pregnancy chat about gender scan, you'll know what I mean!!) xx
