We went when dd1 was 12 months and we stayed in a gorgeous cottage, but for the life of me I can't remember the name. Staying there was lovely and so relaxing. Look on the stayz website and they have a whole lot of child friendly options. Many of the self contained cottages have high chairs, cots etc that they provide. I also think a cottage has more room and is easier with young children.

Not sure about babysitters but the place in daylesford that does the keys for the cottages would probably have people they know and recommend.
