Q: My baby eyes are small.....is there any suggestions??

Hi mommies, I'm a mother of 7 months 17 days old boy baby. My baby isn't crawling yet nor he hardly trying to sit this is putting me into anxiety. So can anyone help out in answering is this fine or is anything I have to do I'm putting him down on mat regularly encouraging him to sit putting toys to reach out all possible things. But my baby is active he started babbling he moves all around the mat n bed n eats well sitting in high chair etc but not doing these 2 things yet. Is there any mommie in the same boat? Help me out
