Since this is our “first” bottle fed baby, I have a question for all you experts. Mouser has been eating like a pig these past couple of days. Then this morning and afternoon, he didn’t have as much interest in eating. I think he ate about ½ of what he usually does. Is this normal? Could his starvation feeling stopped and now this is normal eating? He is still active, going to the bathroom on his own now, but just not as much desire to eat.
