I'm due with #1 soon and tonight my boyfriend and I figured we should test out the baby monitor we got a while back (a VTech audio only one). As soon as we turned it on he got a horrible headache and we had to immediately turn it off. I didn't hear anything and wasn't affected at all so we figure he must be sensitive to the frequency or something along those lines. Has anybody else run into this problem or know of what to do about it? Is there a brand that might be better? I tried looking around on Google but can't seem to find any mention of this problem at all. I work from home so I really want a way to keep tabs on baby as needed but obviously don't want my boyfriend suffering.
