My 9mo has a bottle of expressed milk before bed but I'm now struggling to produce a consistent amount of milk as my supply has dropped ( x4 BF a day and no night feeds). I am wondering whether to top it up with a couple of oz of cow's milk. I know all the advice says not to give it before 1 but I gather that advice is in relation to it being their every feed, not as a small supplement. He has 3 good meals and 2 snacks too. Thanks
