Does any other mum out there have a 3 year old little boy with a lightbulb and battery obsession its driving me bananas. It started when he was about 18 months with batteries, taking them in and out of everything, all his toys, remote controls, he collects them puts them in his bag (over a 100 in his rucksack alone), he does put them back in occasionally. And before any asks he never puts them in his mouth not once he's very careful, he then started with lightbulbs, he found a box of eco ones in our new house and has since then added more and more, if he accidentally breaks one he's absolutely mortified, every time we go to the supermarket or a friends house he seeks them out and really has a strop if he can't have one. I can take him down the sweet aisle or past toys and he's not interested, in fact for his birthday I took him to the toys r us to choose a bike or another toy and he didn't want any of them just the gold batteries by the till. He even takes lightbulbs out of lights when I'm in the bathroom, and yes he knows to switch the plug off, in fact he can undo plugs and remove the fuses, kid proofing doesn't work, he knows which sort of screwdriver to get and cracks on, nothing is safe. I try distracting him drawing, painting, cooking but its all short-lived. The first thing he mentions when he opens his eyes is which battery or lightbulb he wants! Help how long will this last? Todays main interest is the up lighters in our lounge and he's pestering us to take the bulb out.
