Mrscricket,

With my now 5yr old I had a harness for her as she kept running off, it was the older style as they didn't have the cute ones then. After she had been in it for 2-3 months she learnt to stay with mum and when she did go to run off i would tell her i would put the harness back on, this stopped her.

I would rather have a safe kid than and injured one thats for sure.
