Re: Drop in milk supply when expressing
it's normal for supply to regulate, and especially for it to become more difficult to pump milk. it doesn't mean that your baby isn't getting enough otherwise. many mamas have to pump twice to make up for one feed. 50 ml at a pump is actually pretty typical.
and yes, the AAP and WHO etc all recommend nothing but milk/formula until 6 months, and then until 1 still primary food. is there a particular reason you have her eating so many solids already?
sometimes a cold can get your milk down. i agree with PP about taking to bed and kicking the cold out as quickly as possible - walking around with it for 3 weeks must be no fun!
