I also agree that "Holly" is a boy. The peeping at this age means boy. Very handsome though!I watched the video a few times. I do hear a girl somewhere but I don't think it's Holly? The noises that I think are coming from Holly do sound like the beginnings of a male voice, although I still hear a lot of peeping too. Can you do a video where you pick Holly up and carry her away a bit? That will usually cause them to vocalize quite loudly, lol.
Haha I picked her up and carried her away and she was silent, she's only loud when I put her back in with the others which makes it difficult. The two white ones are the girls, and the raspy boy sound is the Seth, Holly is still the only one making babyish sounds, so that's the peeping you can hear. I've got another video where I've put her back with the group So they're all chatting away but because I'm so focussed on her you can sort of see what noise she's making lol.
