hi kymbly. i would stick with milk not water and defo not juice until 1yr old. water is fine a bit later but at this age still milk. as he's now 6mths it's ok to give him milk as a drink not a feed. it's upto you how you want to do it. go with your baby a while longer if i were you. if he still enjoys his milk that's fine, if he shows more interest in his food that's fine too. you could give less milk, 3oz, before his meal so he eats better then offer the rest, 3oz, after eating which he may not want. if you do it that way make sure you offer milk more regular between meals.
you could look at custard and read the labels for low sugar or ask your hv.
hi shady. i'd give her milk feed when she wakes then probably about an hour later try her with breky. i'm unsure if you have weaned her yet? if not she will probably only take 1 spoonfull but she may be hungrey before an hour if not yet weaned so you could try waiting only half hour, then try again at your normal lunch and tea time. give her the same times as you. but she wont try on a full tum of milk.
