Re: Milk supply???
If you don't need the milk I would stop pumping. At 7 months your supply will adjust to match your needs when you need it. So if baby is sleeping at night and not nursing your body will make less milk at night, but continue to provide plenty during the day. And if baby suddenly starts nursing again at night because of teething, illness, growth spurt or whatever else your body will respond and start making milk at night again.
