hmmmm....honestly, this is not a great idea. before your say to yourself, "easy for her to say!", let me just say that i'm a licensed clinical psychologist, and mom of two children. anything under 1 year, or even 18 months, isn't great. i imagine that your husband would find one of two conditions will exist: 1) your daughter will seem "just fine" and go along with your absence without much protest, or; 2) your daughter will be nearly inconsolable much of the time you are gone, particularly at bedtime. this is maybe a false dichotomy, in that there are other grades of reaction she may display between the two extremes, but in any case, this long absence will affect her. if you go through with this, you will notice upon your return that she will be either ambivalent or rather rejecting of you for a time before she reacquaints herself with you. make no mistake: you are the central figure in your daughter's life, and your absences, particularly such a long one (infants have no concept of time), do affect her and will be experienced a pain. i'm not saying, of course, that at age 40 she will be laying on a psychoanalysts couch blaming you for leaving her at age 9 months, but i find myself wondering if there is any other scenario that you can work out, such as:
1) your daughter flies for free as a "lap child" (under the age of 2 years), you hire a daytime nanny in France (you have plenty of time to plan this) to be with her during the day if you are stationary, or someone to travel with you and the group if you are touring France; your husband goes to work and loses no pay (assuming that he would have lost pay, maybe he's salaried?) and gets a week of good sleep and can do some projects for you while you and your little girl are away. you can then put your little one to sleep each night and provide the continuity required at this stage of development. if you go this route, you will need a passport for her, and you'll have to register her with the airline, so don't forget to do that (we forgot to register our little guy with the airline last may and it cost us $500 at check in with the airline. yeesh.)
2) could your husband come with you?
in other words, i wouldn't leave for 10 days if you cannot help it. it's not good for baby, not good for mommy, and daddy might be miserable in trying to make your daughter okay while you're gone. there's something risky about the whole thing. and that's not even taking into account throwing the whole feeding routine (for the both of you) into chaos. that's a whole other issue.
good luck.
