I hear you on the potato thing, I craved mashed spuddies, roast spuddies, hot chips and potato chips right the way through my pregnancy with my son. And then when he was 6 months old and I tried him on mashed spuddies to my absolutel horror he screwed his little face up at it!! He would rather eat pumpkin! I couldn't believe it, what child doesn't like mashed spuddies!! So I kept trying, eventually I started mixing pumpkin in and he fell for it
