I've got some nelsons teething powders for my LO and I was wondering 'in real life' how often people end up giving it to them?? It's so hard to be absolutely certain what's causing a grizzle and I can see myself debating 2-3 times every day for weeks / months about whether or not to give her a sachet. I know the answer is 'when their teething is causing them pain and not otherwise' but I would like to know how often you have ACTUALLY ended up giving them and also whether or not you think they work!!
