Yes, this is jus what you have to do. Exhaustion: I drink a cup of coffee in the morning if I think I need it. I sleep when I can. When I do feel just exhausted, I tag my husband into the ring and zonk out. I'm usually good after a couple of hours or so. I don't really relinquish the need for control. I'm the mama, and he's my firstborn, so I have to find my own way. I knew early on that I couldn't get my feet under me if I always had somebody looking over my shoulder. That's how I learn. When I can't do it myself, I leave notes. I talked with my mother and husband about what was important to me on this journey and asked that they honor those things. We all agree that a baby playing in or near the toilet is not a given. His food does not get microwaved. I give him or approve of his first EVERYTHING.
Regarding schedules, the only one that I stuck to was work. Everything else was optional and depended on how our day was flowing. I still don't have a perfect formula with the naps, but they are soooo necessary. Sometimes we have to either stay home or leave during or immediately following an event. That's just what it is.
I'm kinda anal, too. I had to ask my relatives to come over earlier so we would have time to get him down for the night. Your household is adjusting to a new person. Other people will tell you that you should make the rules and fit baby into your gameplan. I don't do it that way. His needs in this adjustment phase are just as important as ours, so while we incorporate him into what we're used to doing, we also change our routine accordingly.
I think that many of us can relate to not desiring to get out, but at this point, it would be a good idea, even if you just step out to enjoy the sunshine for 10 miutes. If you are used to being more social and value getting "pretty", then you should put it on your calendar for once a month. You will feel better and more energized for it. If you need to sleep for a couple of hours, pick the best two between feedings and let your mother have full responsibility for the baby. Mine is two years old, now, and I still feel like it all falls on me, if I want it done "right". It helps that my relatives (mainly husband and mother) know me and that I give clear instructions about what he eats and...whatever is important to me. I fix his bag and let his father dress him (pre-approved wardrobe), and I send him off. One of my main issues right now is that his nanny doesn't always make sure that his clothes match the way that I would want them to. I relax a bit on this, since they are just at home. I absolutely hate for two-piece outfits to be separated. I have told her that they are only to be worn together. (I can't stand for one to be stained or washed out while the other still looks brand new.)
My typical day at that age--
6:15am - last feeding before work
7:30am - at work
9am, Noon, 3pm - pump
In between pumps - pay personal bills, tend to personal business because my brain didn't really work at home.
5pm - arrive home (Baby stays there all day.)
5:15pm through 6am - nursing on demand
I don't recall how much cooking I was doing, but it happened mostly on the weekends with leftovers for the week. It took me probably longer than most to get my rhythm down, and it's still not perfect. I still nurse on demand from the time I get home to the time I leave in the mornings, but he's not demanding it so much these days. I feed him his dinner at 6:30, and that prompts me to have something prepared for my husband and me.
