Deep breaths.
No, you are not being unreasonable, but you should approach this as you and your husband are a team. Getting out the door in the morning is a team effort and how can you two go about doing that? Tell him that since you are working, you are going to need more help from him with the kids and the housework.
Divy up the duties and do tag-team parenting. While he gets ready and showers, you feed the kids. While you finish getting ready, he gets the kids dressed and teeth brushed. Or something like that.
Be honest and tell him this morning really stressed you out and that you need his help. What you don't need is him ignoring you or brushing you off. Stress that you are a team. It will get easier as you guys get into a different routine.
Remember, it's not just a huge change for you - it's a huge change for your husband too. He isn't used to you needing him in the morning. And if your husband is anything like my husband, he's going to fight you on changing his routine tooth and nail. Although, my husband will step up when I ask him.
I recommend you writing down (physically) how you're feeling and get all the negative emotions out. You should be calm, cool and collected with a sample schedule when you present it to your husband.
Good luck and let us know what happens!
