Can anyone point me in the right direction? He has a tendancy to escape from beds and we have a secure bed at home but we are going to 'brave' going on hol and we are going to put a mattress inside the tent (we are staying in a house) and then zip it and lock it so he can't escape in the middle of the night (my big fear and the reason we haven't as yet been on holiday) He is nearly 6.
TIA
