Squidipa - I have had a thought....

You have been expressing quite a bit of milk, a plentiful supply.You have a lot of foremilk, in fact too much.. By expressing some off before giving Joshie the boob, would mean he gets more of the hindmilk - the really fatty milk and he may gain better.
So maybe you can for an experiment when expressing see how long before the milk changes and that will give you an indication as to ..
A..how long its taking him to get to the hindmilk and how long he is having the hindmilk for and
B.. in the expressed bottle of milk you'll be able to see how much foremilk there actually is.

So express maybe half, give Joshie the boob so he can drain it and get all that fatty hind milk, then give him the expressed fore milk to fill him up! Then if he doesn't finish the fore milk he has got the fatty milk first IYKWIM! Just food for thought!

I haven't had enough to freeze yet but you can get special bags and containers for EBM have a look on EBAY
