Baby is just exploring, relax.

This is completely normal.. Also this must be growth spurt as baby is developing hand and mouth co ordination

Its very normal. Hold baby's hand Play with baby this way u can avoid <br> And Don't takeout figure forcefully ....it may make baby cranky

That's completely normal for a child to do. Babies explore by putting things in mouth. This habit will go away by itself. So, don't worry.
