Rhythm Time at Wiggles on a Thursday morning - I think the baby class is at 10:45 or 11. My LG has been doing rhythm time since she was 3mo and loves it.
There’s Moo Music, on a Thursday morning at Thackley Methodist Church. They do a mixed class & a baby class. I sometimes takes my 3 years old and 4 month old to the mixed class but do the baby class in baildon on a Wednesday x
