Are you a stay at home mom? Do you have the time to take classes with him? We are kind of in a similar boat with just my husband is in the military and this is his first deployment away from his kids...son is just turning 4 and daughter just turned 2 and we are due in June and my son took this separation really hard...even with all the explaination we gave him in advance and everything...acting out in anger...yelling in the middle of the night two or three times...not eating...just everything...I realized the only thing that helped was more time with me...just doing things together constantly...even more than you probably already do...going to the pool to swim, museums, more playdates, TONS OF HUGGING AND HOLDING...he needs to know that YOU are a CONSTANT in his life no matter what else is going on...that YOU are ALWAYS there for him...funny...my parents divorced when I was 3 and I still can remember a lot of things...and I do remember wanting to always be with my mom...even ended up sleeping with her a little bit just to make sure she was there at night...a lot of extra love and understanding.
