I think if you are cutting out bf in the next month or so, going straight to cows/goats milk is just fine. I suppose it depends how much they are eating, but nutritionally, with 3 meals a day and a couple of little snacks cows milk is sufficient. They're growth rate really slows down after the first year, so you don't have to try to ram the calories in quite as much.
I'm the same with work. Although I only work part time, so I get afternoons at home, I miss the mornings so much, and whilst I'm at work, I just get on with it, I find I hugely resent every extra minute I have to spend away from home.
I think its the curse of being a working mother, or a mother at all in this era. As much as we try, we can't have it all, and finding a balance in life once there are children to consider too is a delicate thing at best, an impossibility at worst. I think once Roh is in pre-school in the mornings, it will feel a bit easier for me, although I'm sure I'll feel like I'm missing out on time with F. Its a toughie. I think given the choice, I'd not work for a few years, until they were in school. Then I'd resume a career after a break.
Wsh we all lived in a erfect world eh?
