Such cute pictures!!!!
About the soft, mushy food. Many times JUST prior to foaling, the mama will begin having what we call "cow patties" -- or very loose manure. This is nature's way of cleaning out her system, and giving maximum room for the delivery of the foal.
This leave a greatly empty system, and giving soft, mushy feeds to the new momma, helps her get her system back moving again, and the "extra" water in the food helps to keep her hydrated, and the food moving through the gut. Just a couple of days will help stimulate her gut into working normally again. And if she is normally allowed to graze, then some grazing is good for her too. If not, just some soft mushy food, and some quality hay (like alfalfa) will give her some roughage and protein, and help get the gut moving properly again.
We all look for the babies to poop after birth, but don't be alarmed, if it takes momma a bit longer. Remember, she has a long gut system to refill, and it can take a little bit of time to "fill her up" again.
I'm sure she'll do fine, but if you see something you're not sure about, let us know, and remember we're here to help get this precious one on the ground safely, and keep momma safe and healthy too.
