It helps at my house to have my son's room dark and quiet. I have blinds and curtains on his bedroom window. When it's naptime and bedtime, after lunch, my husband or I take him to his room, close the curtains, change his diaper, read a story and put him to bed. He cries some days, but I let him cry and it only lasts 5-15 minutes. When it takes longer, I go outside or to the other side of the house, so the crying doesn't upset me as much. Regarding noise, for him there either has to be a lot of white noise like a loud stereo or tv or completely quiet.
I think it is a good idea to get your child into a routine now for sleeping. It will be one less adjustment when going to daycare.
Oh, and although my son is a great napper at home 2-3+ hours in the afternoon, when he was at preschool and daycare, it was much less, because of the different surrounding environment.
