Need help with very high maintenance baby!

I am a nanny for twin baby girls who just turned 7 months. The two girls could not be more different. One of them, Nicole, is very calm, has a mild manner, and is a joy to be around. She rarely cries; if she does, it's only when she's hungry or something is wrong (teething, gas, etc.) She wakes up happy, always smiles, and is such a cute baby. However, the other twin, Caitlin, is a huge challenge. She is extremely high maintenance, needs constant attention, and seems to already be spoiled even at the young age of 7 months.

Sometimes I will be playing with Caitlin or in the room and everything is fine, but if I literally turn my head to focus on something else or have to get up and leave the room, she starts screaming. If I pay attention to Nicole, Caitlin screams. If Caitlin is holding something or drinking and the toy/bottle falls, she screams. It is basically like she needs 100% constant attention and care or else she does this loud, piercing shrieking noise. It seems she has gotten worse the older she gets. She isn't actually crying, because there are no real tears and the second you go over to her, she smiles or laughs and stops immediately, then begins again when you turn away. I don't know what to do. Whenever I mention this behavior to her parents, they just blame it on some general reason like "oh, she must just be teething" but I don't feel this is the case. I've tried everything... gas drops, teething tablets, giving her more food, checking her diaper, and nothing helps. It isn't that she's hungry because she will be well fed, it isn't her diaper cause she is changed, and any other thing I try doesn't seem to work. She just wants to be held and constantly given attention, which is near impossible for me to do. I still need to take care of Nicole, as well as get other things done around the house. It is unreasonable for me to have to hold and carry around a baby all day long simply because she wants attention 24/7.

I should also mention that they have a very small condo and the twins share a bedroom (well, it's actually the dining room which was turned into a nursery...) so their cribs are right next to each other. There is really no way to separate them, which makes this even more of a nightmare. If Nicole is asleep and Caitlin is making noise, she gets woken up. If both are asleep and Caitlin wakes up screeching, she then wakes up Nicole, who becomes fussy due to being woken up. It is making my job very difficult, and I'm just not sure what to do anymore. Nothing I do can soothe her, except to just hold her and walk around all day long, which I can't do. She is really starting to test my patience and slowly make me go insane! It would be hard enough if I just had to deal with Caitlin alone, but the fact that I have to watch her sister as well makes this even harder. I feel bad that is is disturbing Nicole, and I don't even want to know what the neighbors in the condo complex think. Does anyone have any suggestions for other things I can do to calm this baby down? Or maybe another reason why she might be so fussy all the time?

I have also tried just laying her down and letting her soothe herself to sleep, but this hardly ever works. She just screams and screams until I can't take it anymore.

caitlin is just like my daughter.
im going to get complete HELL for this but it is the only thing that works.
put her in a separate room, somewhere safe and let her CIO. she will stop.
my sister did it with my nephew (even though moms on here say not to) and he is perfectly independent and happy and 10 years old 

Ds does it too... As much as I hate doing it sometimes we just have to ignore him.... I keep hoping hell catch on soon.

Well... keep in mind it's not her child, so she should consult with the parents before trying this. But if it was her own child, I would 100% agree with what you said.


OP, talk to the parents and see if they are open to trying CIO. I don't think it's something that should be done behind their back, but I feel like CIO works well if done properly. Also, you could look into baby carriers/slings, so when you are needing to do other things, she won't be so upset and you have your hands free.

DD1 was just like that, I couldn't imagine having her PLUS a twin that wasn't able to get the attention she should get. I did CIO the moment I was able to, and even before the recommended 6 months I would lay her down and let her cry for about 10 minutes at a time. (Judge if you want. I had PPD and no treatment for it, plus a colicky baby, I needed some peace once in a while)
I wish I'd had a baby carrier back then.

im sorry, lol ur right. i was just saying thats what i do, but yes she should ask first

Thats my kid 100%. Stick her in a carrier? Thats the only thing that works with my LO.
About the sleeping, no idea, we cosleep so he's pretty calm during the night. But I would seperate the two girls just so the quieter one has a good night sleep, you don't need 2 grumpy babies on your hands.
