This might be an inappropriate question about feeding?

Ok, my husband came home on Leave over Thanksgiving and now he is back in Iraq. As soon as I suspected I was pregnant because my Period did not come last week when it was supposed to, I sent him an e-mail telling him that he might be a father again. He just got the e-mail and responded with mazeltov. He's Christian but I'm Jewish and so he learned that from me lol lol. He brought his best friend from his military Unit home with him and his best friend stayed at my parrents house. Anyway to make a long story short his friend fell in love with my best friend and they went to Reno Nevada and got married. My husband and I went along as the guests of honor lol lol. We forgot our condoms so my husband's potency was fully expressed for the two nights we were there. My girlfriend told me shortly that she missed her Period (coincidentally the same week as mine) and she thinks she's pregnant also. Both of us are married to boys in the same Unit so we will be going to live with our respective husband's when they return from Iraq next year. Both of us will be feeding our babies. I have an 11 month old so he will probably be in day care during the day. Both of us are attending college and want to continue our education. We discussed an idea about taking cles on alternate days and watching each other's baby. She mentioned that since we would both be feeding why not feed each other's baby along with our own baby instead of using a breast pump to make bottles for the other baby. Is there something inappropriate about that? I really enjoyed feeding Jacob and would love having close time with two babies, my own and my best friend's baby. I know she would feel the same way.
