There is no way DF would go.. And practise with the doll.. Oh I'd LOVE to see the look on DF's face then!! I am quite happy to go on my own. It sounds like it will be good..
Definitely try to get him along. Only 3 mums in our class of 16 didn't bring partners. It made a huge difference to my partner's ability to support me. The classes are well worth it.
