Hey! I'm not a military wife but am a first time mom to a 6 mo little girl too and recently I found an awesome moms' group in Springfield, VA. It's not very close to me (30 minutes away) because I live in MD but it's worth the drive!!!! The group meets the second Monday of every month for a themed dinner and there's usually a guest speaker on some type of parenting topic. Ladies sit in table groups and have time to discuss the speaker's topic and to get to know each other. I went for the first time in February and can't wait to go again next week! (Everyone was so friendly!)
The group is called MOPS (moms of preschoolers-but it's for all women of young children/babies) and meets the second Monday evening of each month at Immanuel Bible Church in Springfield, VA (many military families attend this church so I'm sure you'd meet military wives there). The next date is Monday, March 10 from 7pm-9pm. My husband watches my girl for me so I can go; I truly enjoyed it last month!!!!
