RCS, and caring for a toddler

Peanut05

I know to take an easy, and was told not to lift anything beyond 10lbs, etc... My DS is about 30lbs, and although I'm not carrying him, to go through the whole day and not lift him to his high chair, or putting him in and out of his crib is almost an impossibility. MH has been super helpful, doing all that stuff the first few days. But between him going back to work, and my son sometimes crying for mommy to do it, I almost have to resume as normal, sort to speak. Of course, I'm being smart about my limitations, but I do have another child to care for. I'm feeling pretty good for the most part, (9 days pp), but do sometimes feel sore at days end, which I imagine is normal. Ladies with toddlers, how much are you doing, and/or what limitations do you have taking care of other dependent LO's. Thanks!
