Can you pump directly into these bags? It's unclear if there are the correct bags or not

Yes. You can just attach them to the pump and pump directly.

is it pre-sterilised?

Yes they are pre-sterilised which is the great thing about them.

After baby is 6 months old can you open packet from freezer, squeeze out how much you went to defrost and put the packed back I the freezer?

I don’t know about squeezing out but I use the bags to freeze smaller portions of 2oz then defrost and use immediately so I don’t waste a full bag if not needing the full amount.

Can I collect the milk in one bag throughout the day by keeping in the fridge and then freeze it?

This was my daughter, not me, but since she lived with us a lot after the baby was born, as I remember it…. one bag is really only big enough for one pumping session when the baby is older. If you have less milk (e.g. when the baby is smaller there’s less), she used to top up one bag sometimes from the very next feed. But the milk you use to top up needs to be completely cooled in the fridge before adding it to existing milk. There’s quite a lot online about this so double check your particular method to be sure.
