only have to tell them ‘no’ occasionally, then it will mean more to them and you will find it easier if you don’t have to be constantly on the look-out for hazards.
you can also direct your baby’s exploring by having a low shelf or cupboard for toys and other baby gifts that are safe for them, so that they can still be investigating but without danger. this gives you the opportunity to distract your baby from the danger area to the place you have made safe for them, and then both of you will be content.
it is a delight to be able to take your baby to stay with relatives.
