Breastfeeding mamas, any advice on weaning and continuing with weightloss ?

Any breastfeeding mommas out there who were able to lose weight while breastfeeding, wean and continue weightloss ?
So far I have lost all the baby weight and then some. I have been wanting to wean for quite sometime (due to it being way too stressful for many reasons, it has nothing to do with weightloss). I am exclusively pumping and I really want to wean as he will be 4 months old in a week and I feel like I have given my all and my best for my baby and it's time for formula. My question is do I just go back to mfp settings once I am no longer pumping and set my goals accordingly without accounting for breastfeeding ? Or do i do this slowly to go along with the slow weaning process? Right now I only account for -250 calories as we supplement with some formula. So should I drop down to -100 calories and go from there or just not use breastfeeding at all in the database when I start weaning ?
