From what I hear, it's a normal thing to feel guilty as a mother, especially when trying to fill the needs of a newborn along with maintaining what you had with your first child.
I think that when young players really see their game rise next level, it's when practices are like competition and there's no separation there. Of course, there are adrenaline and the butterflies; you don't have that so much in practice. You want to fake yourself out and try to get them there because you want to be as close to that game mentality as you can when you step on that field every single day whether it's practice or in your backyard or down the street with your dad.
A miracle is really the only way to describe motherhood and giving birth. It's unbelievable how God has made us women and babies to endure and be able to do so much. A miracle, indeed. Such an incredible blessing.
Try not to get lost in comparing yourself to others. Discover your gifts and let them shine! Softball is amazing that way as a sport. Everyone on the field has a slightly different ability that makes them perfect for their position.
