Ever since I had DS, I feel like DH and I have lost touch with one another. It's like we're just existing side by side. I don't work, but DS is a pretty high maintenance baby. I'm exhausted by the time DHgets home from work. I'm chronically sleep deprived (yay 4 month sleep regression...ugh). We've just lost our spark or something. I'm just lost. Has anyone been through this and have any suggestions on how to get through it?
