If you just happen to need a potty now, then browsing is a lot of work.

If you know "oh, we will need larger cloths and a potty and some toys soon and that bed will be to small in a bit" you can monitor relevant sites on the side and see when the opportunity comes up.

Not to mention the social circle with parents a bit older and a bit younger. "Hey, we don't need this anymore. Do you?" - "oh it's a bit early, but I take it already thanks!"
