Appreciate your concern. Your son have started using semisolid foods along with formula milk.. So it's completely normal to have a bit of constipation. Altered bowel habits in infants should be of concerned if he is passing infrequent stools with foul smell,/lots of mucus or bleeding.

Greetings it's normal.if the stool again contains blood consult with Pediatrician

Stool color depends up on food which u r giving . As baby has started soft diet . It’s k no problem . If it’s loose stool or any mucus or blood in stool u shld worry .

It's normal.

It's normal

Hello parent! Colour of stool is normal - depends on dietary intake of the baby. You can take the following steps to relieve constipation: - oral sips of water after a feed or meal - instead of potatoes give sweet potatoes - can offer fruit puree of pears, mangoes, watermelon, apple and ripe avocados - be sure it’s of a semi runny consistency and not very grainy - similarly can boil and puree vegetables esp broccoli, spinach or any other greens, pumpkin, carrots, etc. These can be mixed with one another or in khitchri too

It is normal , if it continues it should be a concern
