I went to the Lawn one and it was very busy. It is not structured, so you can just turn up with your baby at any time between the times shown. Mine started at 0930 but didn't fancy getting up early, so I just went at 1030. There is a volunteer who "runs" the session, but you generally have to tidy up after yourself when you are done. I say "run" loosely as I only saw them at the start to introduce themselves, but after that, you are on your own.
I went to go to one at Shears Green today but the timetable has changed, my HV didn’t send me the right one🤦🏽♀️ my LO doesn’t usually wake up until 9 so we will see if we can make the morning ones👀
I'm going to my first one on Thursday! At the lawn 😄 my little girl is nearly 7 months. Worth a try!
