DS has just turned one and is having 3 bottles a day. He has cows milk morning and before bed, and 1 year + formula at lunch time. I know the general consensus is that the growing up formula isn't necessary, but he isn't having much solid food at the moment, so I want him to have the growing up formula for now, until his appetite picks back up.
He's also a sippy cup refuser, which is why he's still on bottles... I'm working on changing the midday bottle to a cup.
Do I still need to sterilise if using cows milk? I wasn't sure if it was just for formula.
