Nursing/bottle feeding

I plan on EBF as I have with my other kids. Was going through my breast pump pieces today and realized I'm running low on the medela bottles I use to pump in. But when I go back to work, I'll have to have bottles for feeding. How many bottles do you think I'll need? I have 5 of the 6 oz bottles and 5 10 oz bottles and it just seems like it won't be enough unless whoever is watching him during the day will wash the drinking bottle out to reuse for the next feeding... idk maybe I'm over thinking it
