my vote definitely goes for anything that plays a tune or makes a noise - I hate them with a passion :0
And now a question for all you who got so het up about Zebra's comments - at what age do you start changing your kids at bedtime ?
I have a 9 month old who generally go to bed in whatever they are wearing, usually minus the outer layer. This is because a) the clothes are not dirty - usually a babygro anyway, b) they hate being changed - so not worth the screaming and the agro.
I have a 2 year old who I thought was fairly typical - he normally goes to bed in pyjama bottoms and whatever he was wearing on top through the day - a compromise which usually we get to without a major fight.
My concern is normally making sure they will not be too warm or too cold - what they are actually wearing is secondary.
Clothes are generally changed when dirty or just tired. Usually dirty involves food, water, or mud in the case of the 2 year old. Baths are usually for fun, rather than routine, and are followed by clean clothes, and often a lot of screaming as they hate getting dressed again (hence no routine bath - it takes all the fun out of it if you have to wrestle hysterical kids back in to clothes afterwards).
Reading this back I seem to be more along the lines of Zebra than many of you. Maybe its because I have 3 under 3 ?
