They are more to prevent him from running off upstairs again when we don't want him too.
It was the casual way he opened it this morning and we haven't seen him do it ever before!
We have three gates though and the upstairs two I don't think he can work. They involve a pinch and slide movement that I hope keeps him foxed long enough for DD to get the hang of stairs. Then I'm happy to take them down.
DD loves climbing them and patting the stairs as she goes.
Well, after a nightmare bedtime last night - which involved him climbing under his mattress and lying between the bed base and the mattress, the unpacking of a whole box of baby ear buds "mummy, I cleaning my ear" and then on subsequent trips to return him to bed finding more of the cotton wool bits and him handing it to me saying "snowman" (but in German) and me trying not to laugh it took two hours for him to go to sleep.
Tonight it took DH about 20 minutes
DS was pretty tired though. My turn again tomorrow...
