my breastfed baby is 5 months old now and drinking about 120ml-150ml per feed, 8 times within 24hours. I'm gg overseas in October (11days) and I'm planning a stash for my absence. I will start her on solids next week. will her milk intake drop by October? she will be 8 months old by then.

The total amount of milk consumed in a day will likely decreased as you start introducing solids into her diet. However, I would think that it is still good to start building a stash now. As a guide, you can refer to this article: https://www.singhealth.com.sg/PatientCare/ConditionsAndTreatments/Pages/Food-and-Nutrition-Weaning-Child.aspx The table gives a good summary of how the meal times may look like. Hope this helps! :)
