My husband has a wonderful opportunity with a new job. He will be gone 40 straight days for training. (Leaving tomorrow)

After that, he’ll be working 20 on 10 off. We have a 17month old and a 2 week old baby. I guess I’m looking for advice/reassurance. How do you get through this? I’ve never been away from him for long periods of time and just wanna know how I can stay strong for the family?
