Once a baby reaches about 8 months or so, they become much more alert to everything that is going on around them. They’ll realise that you are moving around doing the housework tasks, and will notice that the phone is ringing, or the radio is on, or someone coming to the door. All this means that they are highly distractible, so that almost any activity they are doing can be interrupted by anything else that is going on around them. This new behaviour may surprise you, but it’s because your baby has developed enough to notice the world more, so has found that there is lots out there that they don’t know about, and want to learn about. This is the time when you have to be very aware of all the interesting but dangerous ordinary things in the house, like electric sockets, lamps, and ornaments that can be pulled over and much more.
You may find that you have to give your baby one of their baby gifts and then change it for another one fairly soon so that they don’t get bored and fractious. You could keep the toys out of your baby’s reach, so that you can always find something that they haven’t seen for a while, which will hopefully seem new and interesting to them again.
