The question you need to ask yourself is if you are physically overwhelmed, or emotionally overwhelmed (the answer might be that it’s a combination).
If you simply don’t have enough time to do all you need to do, you might need to hire some (more?) cleaning help. However, it’s likely that you’re mostly emotionally overwhelmed. If this is the case, it might just be that you’re feeling underappreciated. Don’t blame your husband for it; we guys just don’t get how difficult it is to run a home and take care of a baby. If he were asking, I would tell him to make sure he lets you know how much he appreciates all of your hard work and to help out more, but he’s not the one asking.
So here’s my advice, and it’s good advice even if I’ve misdiagnosed the issue: make sure you let him know how much you appreciate what he does. He works hard to bring home a paycheck, and still has the good sense and decency to pitch in at home. It’s important that you mean it, too. If you make the effort to show your appreciation for him, you’ll feel better about things. And who knows? Maybe he’ll reciprocate and show his appreciation for your hard work and efforts as well.
Hatzlochah, and much nachas from the baby.
