my 4 month child is not passing stool for 6 days what to do

A. Hai good morning !! Do tummy massage - Apply warm coconut oil or castor oil gently massage for 5 minutes in clockwise direction with finger tips . This helps in relieving from gas,constipation,tight tummy issues. Generally few new born babies constipate if baby is active ,taking feed normally without gas ,tight tummy issue no need to worry.
