The problem with babies is that the older they are, the harder it is to train them to self-soothe. It will take work, but it’s worth it. First night, put her to bed and soothe her (you know what she likes) with calm music, a crib mobile, back/stomach rub or gentle stroking. After a few minutes, when she is calm, leave the room. She may be a little unsettled, and if this is the case you should go back in every ten or fifteen minutes and repeat until she is sleeping. The next night, cut back the number of times you go in the room, and the night after that, cut back again. Eventually (it could take up to two weeks at that age) she will learn to put herself to sleep. I did this when my oldest was three months and it took a few days (she was NOT easy to sleep train).
Good luck!
