As for the bottles - my 2 year old (ds1) can't seem to go to sleep without his teat bottle - and while I have tried to move to a sip cup, he won't and am not prepared to fight cuz I do think he will eventually grow out of it. He actually puts himself to sleep. We have a strict rule that he does not lie down with his bottle (which can cause ear trouble), but he sits up in bed, with his teddy and drinks his bottle until he falls asleep. He talks impressively well for his age and pronouces some very hard words already, so I don't believe this thing about bottles causing speech trouble.
About the starch issue - I think the nutrtion lady has a point about it not being a good idea as a first food, but I disagree that it should not be used until they are one. Starch is more comlicated to digest, but it is definitely digestible. My view is that you don't use it until their little tummies have at least passed a weeks worth of simple and plain fruit or veg when you first introduce solids - after that, once their tummies are used to the different food, then introduce.
This reasoning is not as broadly known as I think it should be, but even still, most of us were probably fed baby cereal from early on. Granted, many people our age do have digestive trouble of some sort, but it is correctable by lifestyle changes and natural methods (often, anyway), so all is not lost if it is something you've given already.
My true belief about all this is: just trust your mothering instinct... your child is unique and no fundi's knowledge can really replace what your intuition can achieve if its properly listened to.
