well, I have tried to intro cow's milk numerous times with the same screaming wake ups from a sore tum...
Tried Natrel's Baboo milk as it is supposed to be a good transitional product (lower protein that milk but slightly higher than formula) and similar nutritional profile otherwise. Today was day two. Yesterday I gave her 2 ozs Baboo and 6 ozs formula in her nap bottle (all formula at BT though) and she did wake and holler but resettle on her own easily. Today, I did 3 ozs Baboo and 5 ozs formula - woke screaming just over an hour into her nap (her cycle is about 1 hr 5-10 mins now)... would not go back down. Crying, wicked burping... clearly uncomfortable.
I give up. She takes a vit D supplement and is totally fine with cheese and yogurt so I am going to stop the milk trials now and just wait until her last case of formula is gone.
So, just to torment myself, I am going to wean her from her bottles over the next few weeks as well. Joy. This could be a bumpy ride!
