Totally agree with the other posts. However, my DS went through the same thing, screamed the house down if someone other than me or DP held him. Now that you mention it, it was only my mum, sister and MIL that he cried for too, but none of them wear perfume, so I didn't link it to anything. I just thought it was a bit of him just wanting only his mummy and daddy. He's got past it now and will happily be cuddled by others most of the time.
