Hi Davina,
Both myself and my other half are FO's with a mini-me in tow! She's straight! (There goes my fantasy!)
Anyway, were both on the same fleet and the hardest bit is juggling our rosters, so that at least one of us is at home.
We have 30+ female pilots here, both left seat and right. A large percentage with kids and partners in the airline.
The main problem with the job is the unusual hours associated. On short haul you can either start your duty very early or finish very late. On long haul you obviously end up spending quite a few nights away each week. You'll need either a very understanding partner (not sure if they exist!) or an au-pair/nanny. (Ours always chosen by the other half and with a BMI of 30+)
A large percentage of our female pilot with families also tend to opt for part time conditions.
Other than that, no different from any other job with shift work.
Hope that helps!
