Does the baby continue to cry when held? Our little guy will wake up in the night (most likely due to teething or growing pains) and if he won't stop, we will bring him into bed with us - right to sleep he goes! I am a huge fan of doing what needs to be done in order for the family to get some sleep, especially if everyone has to work the next day!
Just remember, or tell her to remember, they won't be crying at night or sleeping in bed with us for much longer. We really will miss it, if we can see past the exhaustion right now!
Also, I would tell her to do a bottle as an absolute last resort.
