Hello...
How strictly do you follow the Throw-Away-After-2-Hours for formula milk rule?
I am weaning DS off the breast, and have moved him onto solids and sippy cup. Sometimes he only has half his sippy cup milk, and throwing the other half away seems wasteful...
The other thing about a sippy cup is that there is always about 50ml left that he can't get to because he doesn't like to drink with his head tilted back, so I always fill it to 150-200ml.
I have once or twice allowed him to drink from the same milk after 2 hours, while we are out and about... How bad is this??
