I'm glad your husband is missing you. That's a good thing. I hope that not living with family will help you both.
As far as your daughter is concerned, I think it's the whole kit and kaboodle that is so hard for her, not just her dad being gone. I'd keep her pretty busy and on a very strict schedule. If you have ever had her in daycare, use a daycare-like schedule. It will really help. If she has meltdowns, be kind but firm. Don't yell or get mad at her. If she is awful, just tell her that she must be tired and put her in her room until she "feels better". That will give you a break, and her a break. When she is ready to come out, give her hugs and tell her you love her. That doesn't mean not to discipline her, but putting her in her room because "she must be tired" gives her an out that she needs right now. And she REALLY needs for you not to get angry at her.
I think having a good schedule, same times to rise in the mornings, eat, nap, playtimes, and bedtime along with once a day Skype talks will be fine. Even if the Skype talks can't be that often, it's okay. She will get used to this.
When your husband DOES come home, it is very important not to change her schedule. Explain that to him and ask him to work with on this.
Good luck,
Dawn
