I've got mine plugged in underneath his cot as it's the only plug socket I have too. It's the first night of using it so can't comment on how it works
Plug socket under N2M crib too and it worked wonders for us and helped me our little girls dad too xx
I don’t know if it needs to be a certain distance from the cot, but my only plug (extension lead) is under his n2m. It worked wonders, he was very bunged up and had a terrible cold but it definitely helped after just 1 night! Used it for about 5 nights I think. I don’t think the sore throat would be linked?
