Am on mat leave with DD1, who is now 15 weeks old. I'm not planning on going back to work for a while yet, but I've been asked to take part in a special, one-off project in about six weeks time. It's very high profile and would be really good for my career. But I'd have to spend a week abroad and away from my baby girl - it wouldn't be an option to take her as it's in a developing country. She would be about five months by then, I'm no longer Breastfeeding, and she'd be at home with my husband and a nanny who is a family friend who I'd hire to look after her when necessary (DH is freelance and can be around a lot). My DH is happy for me to go.
I can't decide what to do. Would I be unreasonable to go? Obviously I'd really miss her and that would be tough, but would it be unfair on her or damage her in any way?
