Tongue thrust reflex (protrusion)

When and how to introduce solids is a matter of concern for many parents. Experiences will differ, as will the advice given by family and friends. If food is being pushed back out of their mouth, it is a sign that they are not developmentally ready, and it is best to wait and try again the next week. It is recommended by the World Health Organization that babies do not start solids food until around 6 months.

 

What is Tongue thrust reflex?

Tongue thrust reflex or extrusion reflex is an involuntary action in young babies where their tongue pushing forward when something comes near or touches their lips. It is there from birth to stop a baby from choking and helps them to latch on to a nipple. If something accidentally enters your baby’s mouth the reflex will push it back out, ensuring only milk feeds enter their tummy until they are ready for solid food.  Tongue thrust reflex is a sign that a baby is not ready for solid foods as the tongue will push food back out of their mouth.

 

Is my little one ready for solid food?

There are several other signs that a baby is ready for solid food and if they are all there and they are nearing 7 months, then solid food should be introduced even if tongue thrust reflex is still present.

If after 6 months tongue thrust is still present, trying to stop them using a dummy or sucking on their fingers might help, as they both encourage forward tongue movements. Using a cup with a short straw for drinks makes the tongue go back in the mouth and helps to eliminate the reflex.

 

Feeding tips

Parents often worry that a child pushing out food with their tongue means they do not like the taste of the food being presented to them, but this is not the case. Try placing pureed or mashed food at the side of their mouth using your finger, or trying soft finger foods. Their tongue will move towards the food and be less likely to move forward.

It is also important that a baby is sitting in a secured upright position with a footrest when feeding. Sit at their eye level to keep their head central, so that their tongue will be positioned correctly in the mouth.


Tongue thrust reflex will begin to fade from 4-6 months as your baby develops. If it is still present after 6 months, it does not necessarily mean there is a problem. 

If you have concerns about any aspect of your child's development, please seek advice from your health visitor or GP to rule out any underlying health conditions.
