so DS has just turned one and is off the fomula and took to cows milk really well, he slept through the night from being six weeks old (I thaught I was lucky) but the past month he wakes around 12-1am for some milk, I used to keep ready to feed formula next to my bed so I wouldnt need to go downstairs ect..but now hes on normal milk so I was wondering does anyone use the cow & gate growing up milk? and would I be able to give him ready to feed cartons of that at night if he has normal cows milk in the day? or should you not mix milks?
