My DS is 3.5 months old out - he will not feed ( yesterday between 10 and 3.30 pm we were out and DS did not take the breast out of the house - I had expressed breast milk and gave it to him in a bottle, but I would not like this to be a routine..). I tried to go to quite place and feed him - but still he did not take he breast...At home I use nursing pillow - could this be the reason that he is used to the nursing pillow?
