It is better to see your doctor if in any doubt. Developmental problems manifest themselves as inability to achieve a certain milestone timely. Track your baby’s developmental milestones with a chart (available online) so you can detect any abnormality early and seek medical help.
Your baby is an expert in rolling over and back. If you continue the simple exercises I mentioned earlier, your baby will show excellent muscle strength. Your baby sits with his hands supporting his posture. Then your baby may progress to sitting without support of his hands. His fine motor development is fast. He reaches out for stuff with one hand and he reaches further than in previous months. He handles small toys well and transfers them form hand to hand. He has ulnar grasp. This means he grasps small objects with the edge of his palm near his little finger.
Now your baby has full color vision. He can track object across the field of vision much better by now.
Your baby’s social interactions have now matured to a stage where he can identify emotions by the tone of your voice. He responds with no. He babbles continuously with strings of consonants. Your baby now expresses emotions by using his voice.
He can now find partially hidden objects and when he does he expresses approval vigorously. He loves to play with other people and shows his displeasure when play stops. He communicates with noises. He is now really interested to see himself in the mirror.
Common illnesses run rampant these days. Don’t be alarmed.
