I have a question or two I had a intake today for a local program today that offers classes for baby stuff up to 3 years

I am breastfeeding and pumping she was talking about a bra that goes over the pump has anyone heard of this and if you own one what's your thoughts .

Second question * not trying to start a bashing vest looking for honest options on the subject * She told me I should bf until Serenity is 3 .
In your thoughts what age would you recommend stop bf at .
