How long to keep puree veggies in the freezer?

[Racers]

I've started to build up stocks of pureed veg for when the time comes to start DD on these but I haven't seen any recommendations about how long I can keep them for. Any ideas? If it's not very long I might have to stop production for a while!
Thanks,
Clare.

I have Annabel Karmels babycook book and she say 6 weeks, hope that can help you. I have also made a large stock of ready made veg/fruit puree for my little man
