I am in the same boat. I return to work 30th Jan and I am not looking forward to it.
I am currently looking at breastpumps so I can continue to breastfeed while back at work.
At the moment i like the Avent breast pump in the return to work kit. Looks like its good idea with all the bag bottles and ice packs.
its $165.00 but might be a good investment.... would be cheaper than buting formula all the time I guess.

If anyone has used Avent breast pump please letme know what you think?
