Daughter doesn't want to nap

My wife's job has been having her work more hours so she's not home as much. I work from home as a video editor. We have a 2 year old daughter and lately she's been not wanting to not take a nap at all and constantly play. Shes also very interested in my work and wants to be in my lap while I work, but also mess with the computer which can mess everything up. I try to get work done when she's napping, but she doesn't seem to want to nap. At least not at a decent time. She will want me to lay on the bed with her and she will "sleep" but as soon as I get up she yells daddy. She will eventually try to sleep at 5, which I know is not good because she won't sleep at night, but when I am so behind on work and its the only time I can get anything done then I just let her. Any advice on getting her to sleep during nap time?
