"He's healthy and well fed, that's what matters"
We've been supplimenting the formula for months. I have beat myself up over it, stressed about it, and eventually accepted it. There was no way I could pump as much at work as my son was drinking and I never built up a proper freezer stash.
My husband responded with the above quote every time I started to beat myself up. And he is completely right. Some breast milk is better than no breast milk. But even if your child is completely formula fed all that matters is that they are getting enough nutrition and are healthy.
Once I saw the change in her.. after a full belly.. it was all ok and she's super happy and it was the best decision I made..
