Hello! You've got it good! Be thankful! :)
The way I am reading your request is your daughter is 7 weeks old and is awake from 11AM to 8:30PM - with no naps during the day and all other times is sleeping, correct?
Here's the best way to ensure your child is healthy:
1. wet diapers - she should have a wet diaper at EVERY feeding. They should not smell bad or be bright yellow, they should be pale yellow to clear.
2. color of bowel movements - if she is breastfed, they are usually mustard yellow. Formula - can't help you there.
3. When she's awake - is she focusing on things? Smiling? Can she hold her head up on her own (ooooh, it's been sooo long (7 years!) I need to think about this one!) As long as she's not acting lethargic - you know, slow as molasses - she is fine. She should have reflexes to sound and light and be able to move her limbs - okay, she's not in control of them but her brain is putting the pieces together for her! :)
4. The whites of her eyes are WHITE, not yellow.
Personally, I wouldn't let her sleep to 11AM - I would wake her up after about 2 hours (8AM) for a feeding or interactive play so she will nap from 11AM to 1PM. But that's me - what's important is how this works with your schedule and life.
I NEVER stopped my life for my kids - I didn't turn the phone off and didn't NOT vacuum. My SIL did this and her kids are VERY light sleepers, even the 21 year old wakes at the slightest noise. No kidding or exaggeration.
I would plan my day(s) around my kids napping times, but there were times when that couldn't be helped (Dr's appointments, etc.) but instead of being crank-monsters, they handled it well.
I hope this information helps you!
Take care!
