So I have been feed my daughter similac, sensitive, the orange tub since a few days after she came home from the hospital, the regular kind she would just let it sit in her mouth and it would flow out all over her.

Anyways.....

Since she came back from spending the night at my aunts she has been spitting up a lot. Almost after ever feeding. She is almost 2 months old, and I have fed her 2 oz, a little bit of spit up a little after burping is finished. 4 oz, the same deal. 6 oz, same thing.

I have noticed that when my aunt fixes her bottles, she fills it up, let's her drink as much as she wants, sits it down, more than an hour later she will still be letting her drink the same milk from before. I read on the formula tub it says use the contents within an hour after feeding begins. Could this be why?? Because of all the old milk she's been drinking?? I don't know....she doesn't have a fever, she's not fussy, she's just how she always is a happy baby.
