"Parents may be concerned that their baby will choke.But although anyone, in theory, can choke on anything, nature gives babies a natural prevention against choking by teaching it to chew before it can swallow. The risk factors are if a baby is not sat up straight, and if suction is introduced, such as the action involved in sucking off a spoon.
Rapley explains: "Imagine eating tomato soup - you suck it in. Now imagine eating minestrone, a mixture of liquid and solids. The way you eat it is different, you can't suck it in, you chew it." It's because of this that purée-fed babies often refuse second-stage baby foods, which involve lumps and purée. They don't know whether to suck or chew so, as a natural defence mechanism, they do neither......
.....Introducing solids is a complex physiological state the baby has to arrive at; he has to be immunologically ready, he has to be able to produce the enzymes to digest the food and he has to have lost the tongue-thrust reflex and be able to chew and swallow food.
Tongue thrust is a protective mechanism that all babies have - but it can be overridden by spoon-feeding. Their tongues will push out anything they can't handle. As a baby gets older, its tongue-thrust reflex is triggered further back in the mouth until it eventually disappears."
And this one too,especially this part;
"Won't he choke?
Many parents worry about babies choking. However, there is good reason to believe that babies are at less risk of choking if they are in control of what goes into their mouth than if they are spoon fed. This is because babies are not capable of intentionally moving food to the back of their throats until after they have developed the ability to chew. And they do not develop the ability to chew until after they have developed the ability to reach out and grab things. The ability to pick up very small things develops later still. Thus, a very young baby cannot easily put himself at risk because he cannot get small pieces of food into his mouth. Spoon feeding, by contrast, encourages the baby to suck the food straight to the back of his mouth, potentially making choking more likely.
It appears that a baby's general development keeps pace with the development of his ability to manage food in his mouth, and to digest it. A baby who is struggling to get food into his mouth is probably not quite ready to eat it. It is important to resist the temptation to 'help' the baby in these circumstances since his own developmental abilities are what ensure that the transition to solid foods takes place at the right pace for him, while keeping the risk of choking to a minimum.
Tipping a baby backwards or lying him down to feed him solid foods is dangerous. A baby who is handling food should always be supported in an upright position. This ensures that food that he is not yet able to swallow, or does not wish to swallow, will fall forward out of his mouth."
