Need for milk bottles

I’ve had an email to say that I can start the residency at the hospital on the 19th September, I really need more milk bottles. I have collected quite a few and they are going to collect them at the bluecoat which will help a lot. I just can’t judge how many I’ll need, I think I’ll have enough for the first session though and will be able to take the ones from the bluecoat home then so hopefully I’ll keep a good stock. I think I might put a call out on facebook too.
