DS is 27 weeks. We've been weanig him for about 3 weeks. He was fine at first - lapped up baby rice, then carrot, then sweet potato. Last week it all went to pot - he had a cold and was teething a bit so maybe that was what stgarted it. But now he still won't eat. He's had a bit of mushed banana yesterday and I've tried everything with the other food, made it runnier, made it with baby rice, made it with extra milk etc, but he just blows raspberries whenever the spoon goes near. He\s not interested in BLW either - won't put food near his mouth - just looks at it and drops it. I've got all these blooming cubes in the freezer and he's not having any of it. SHould I be worried or is it normal for bubs to go off the idea of solids completely? Whats the latest that babies can start weaning by?
