Yay! You made it outside! That's great. I bet the fresh air did those kiddos good! :)
I know that you have been worrying about Chase and this milk allergy. My son had open heart surgery when he was 3 months old. Since surgery he refuses to drink a bottle. They thought it was a milk protein allergy so they put him on Nutrigenin which is similar to the Similic Product you wrote about. Brody is now ten months old and we go to a speech person every week to help us with our feeding issues, because the Nutrigemin was so gross that he refuses to take any kind of bottle. Stick with the breastfeeding if you can!!
