My son doing both, at the moment he prefers the manual but sometimes he prefers the electric.
My daughter has seen a frozen electric one and asked for it. She used to be amazing with brushing teeth but she’s having a little defiant moment at the minute and she’s got about 5 toothbrushes because she likes to choose so I’m considering getting her this one as it’s a bit more fun and then she can do it with us ( we have electric ones)
Where have you seen the frozen toothbrush mine love frozen and are being monkeys with brushing their teeth, it might help.
@Nikki the oral B ones you can attach the stickers you want, I have the Spiderman one but there's also frozen. You can find it in any big supermarkets or on Amazon
Surprisingly getting on really well. Seems to prefer it better than a manual. We've been using it for about 3 months. I didnt think he'd like it but its gone down a treat.
