My sister's husband is leaving today for Georgia and then Iraq. He will be gone for at least 18 months, if not extended to 24. She has an almost six month old...who is NOT an easy baby! I will be watching him during the day while she is at work, but she still has those night times to deal with (he still gets up during the night) and weekends. I went through a deployment three years ago, but we didn't have any children at that point. I know how hard just not having your husband there can be. Like the other two said, the best thing to do is just keep busy....it makes the time pass by a whole lot faster. I also found that filling the bed with pillows made sleeping easier. As far as the parenting alone goes - find lots of people to help out and give you some adult breaks. Take care of yourself and look forward to the next phone call. Also, it will be hard for your 3 year old, so talk about Daddy a lot and make things to send him. I got through the time by organizing fundraisers for my husband's unit. It made me feel useful and passed the time because I was so busy planning. I hope some of that was a little helpful!
If you need/want to chat, both my sister and I would love to talk to you. I have a feeling in a few weeks my sister is really going to need some other women around who know what she is going through!! My email is ____@____.com sister's email is ____@____.com luck to you!!
