A few years ago when my son was a toddler I waited on the grass while my then husband joined the queue and just followed him slowly, taking lots of breaks. It was a massive pain in the arse for him but nice for me and my son. No one seemed to mind.
we camped in Cockmills a couple of times and it wasn’t a restful Spot. At the time we wanted to be near the Kidz field and all the other parts of the festival on that side but the last few times I have chosen Wicket which has lots of benefits including the fact that the long walk to get places can be varied so that the adults get to walk past stages and see/hear some music and also the kids are not close enough to the Kidz field to continually ask to go there. Win win if you ask me.
