First off congratulations on your daughter. It is an amazing time!
You are free to move back to the UK with your husband and small bundle of joy.
If you want to do it under EU law, then you (EU citizen) need to intend to (eventually) work in the UK, though I am pretty sure you do not need to do it right away. EU law can be used because you have been exercising treaty rights in Italy. See
http://eumovement.wordpress.com/2007/04 ... ional-law/ for an example. He simply needs to apply for an EEA family permit. Does not matter at all whether your husband is currently or has ever worked.
You can also apply under Uk law, but that is more expensive and it is likely not so easy.
Is your husband anywhere close to getting Italian citizenship?
