I really need some help or support or suggestions! Anything! Here's my situation:

I work part-time doing in home therapy with a family. I have been there for 4 years. The mother has 4 children age 9 and a 15 year old. The therapy is much less intense now then it was and now we mostly watch them, help with social skills, and help with school type work. When I got pregnant, she offered to babysit my DS while I worked. She also allows me to nurse him there instead of having to worry about a bottle. It is great because my son comes to work with me, I get to nurse him, I don't have to be away from him, etc. The only problem I have with her is she is a little old school. She is from the babies manipulate so let them cry it out school. My DS is 3 1/2 months and she has been pressuring me to have him on a nap schedule (which we are working out a routine now that he is older) and she pressures me a lot to let him cry. She expects him to lay down and go to sleep on his own for naps. I am very against crying it out and I think it is kind of ridiculous to expect my baby to be able to just go to sleep on his own at this age. If I could quit, I would. I plan on being a SAHM but I won't be able to quit for many more months. I have to work and I can't afford child care anywhere else. I really am blessed to be able to take my baby with me and I love the family I work for. This is the only issue we have and I just don't know what to do. I have expressed several times that I won't let him cry it out and she has hinted a few times that she doesn't have time to be at his beck and call when it comes to sleep. Any help would be so appreciated!
