Blowing bubbles, can be observed in some babies between the second and fourth month. It is a sign that your child is experimenting with his mouth – a healthy sign that would indicate that he is getting ready for speech development in the future.
Research shows that babies who “blow bubbles” and display other complex mouth movements like licking lips tend to pick up the language more quickly as toddlers. However, do not worry if you see your baby is not doing any of these activities. You can interact with your baby and try to show her how bubbles are blown. Your newborn will be keen to mimic you and try out this new move.
There is another tale behind blowing bubbles, though. Apart from it being a fun activity in which your baby is increasingly getting hold of his tongue, palate and lips, your baby may also blow out spit bubbles. This happens when babies produce more saliva in their mouth than what they can swallow. It is generally characterized by bubbly spit coming out of the mouth. The baby will have bubbles on the lips and saliva will be spotted slobbering all over hand, neck and shoulder.
There is nothing to worry, however. With time, as their swallowing reflexes mature, your baby will grow out of this habit. In the meantime, just keep on wiping off all the excessive spit from around your baby’s mouth to avoid bad smell and bacterial build-up.
