At this stage, the movement of limbs, head and other parts of the body is always something to watch out for in your tiny bundle of joy. Your sweetie pie is just 3 weeks old, and now it is the time that her movements will mature slowly and steadily.
What you need to know
At this point, you notice that your baby will try to look side ways with sound or hanging objects. It is a great way to understand if your little one is hearing well or not. The head movement side ways is a positive sign of muscular strength, hearing and eye ordination. You can actually sit back and relax that your little one is doing great.
However, refrain from making the tiny head move again and again, as it might end up hurting the little one. Babies are fragile and must be handled with utmost care. So, for now, have fun with these cute movements and enjoy parenthood like never before.
