my baby is 3.5month old and he is using his left hand more than right hand his right hand grip is also loose incompare to left one should I get worried? But he also put right hand in his mouth and unclench it.

A. To understand this 90% of the kids are actually left hand dominated only and we as Indian specially in Indian culture we push for our child to use the right hand all the time and that is how slowly you will see the child adapt on the right hand but most of the kids are left hand oriented there is nothing wrong in it
