25 weeks pregnant. Weaning 17 month old. (August 6th 2018)

Im 25w pregnant currently nursing but weaning my 17m baby.

I know she gets very little when she nurses because she stops right away and tries to nurse on the other breast.

My questions is - if shes completely done with nursing buy the end of August 2018,. will i start over and produce milk like i did for her when she was born?

or will my body stay in the non production mode and just not make any for my new baby. my new baby will be born in November 2018.
