This is completely a first world problem and prepared to be told IABU! Sorry for length, trying to avoid a drip feed.
We have a 7mo DD and DH is a great dad. He's on shared parental leave and understands the demands of a baby. However, as I BF, I've done all the night wakes (he wouldn't mind doing them and did all the night nappy changes, it's just I have the boobs!). I've always loved my sleep and have struggled with the broken nights - I'm a worrier and lack of sleep makes me anxious and teary.
DD isn't a bad sleeper, but she wakes once most nights, and likes a 5:30/6am start to the day. DH is much more able to deal with lack of sleep than I am. He also sometimes unintentionally keeps me awake as he's a restless sleeper.
DH's main hobby is travel, and in particular collecting points to get really nice holidays cheap. We've had some fabulous long haul holidays over the years as a result. We've been on holiday once since DD was born, to Portugal last month - she was ok with the travel (2.5hr flight, in the day), but didn't enjoy being late for bedtime in both directions. DD spent many months taking short naps and has FINALLY started napping for longer periods, but only in a cot - she will nap in pram / carrier but only for 30/45 minutes. As a result, on holiday, I insisted she took her first nap in the villa every day to make sure she got one good nap a day. DH went along with this, but wasn't happy that we were "wasting time" rather than getting out and about.
DH would now like to do a long haul holiday when she'll be 10mo. He has a flight voucher that expires at the end of the year that would let us fly first class affordably, but can't be used for travel in Europe. He doesn't mind where we go: for him it's about having a luxury flight and exploring a new place. But I'm really nervous about taking DD on a long flight (6hrs+ with at least one direction being a night flight) and more importantly, the impact on her sleep and so mine of a 4+ hour time difference. I'd prefer not to use the voucher and instead do another holiday in the UK / Europe, but he thinks this is a waste of the voucher and the holiday wouldn't be the same without the luxury flight. He reckons DD will be fine if we just go with the flow and if not, we just won't do long haul again for a while.
I think we all won't enjoy a long haul holiday at this point - DD's too young to appreciate it, DH will be frustrated it's not the same experience as child free, and I'll be anxious and exhausted. AIBU?
