I am not sure where to post...so, I figured this fit the best. Anyway, DD3 will be 1 in just 2 weeks (OMG!). She has been very interested in DD2's sippy cups from the time she started crawling. We have given her both water and juice in sippys every once in a while. Today, I was taking a shower during lunch time and came down to find DD3 with whole milk in her cup. DH said she just screamed and screamed when she saw DD2's cup (totally normal for her to do that) and he decided why not try it since we are so close to the 1 year mark.
Other than an allergic reaction (which I doubt will happen) is this really a big deal? It's not like we replaced a normal nursing session or bottle with whole milk.
