tips on how to get little one to sleep

so my little one has hit the rolling milestone. he doesn't like to sleep anyways so it has been hard to think of ways to get him to sleep. right now nursing him to sleep is all that works. I used to Pat his back until he got really tired or fell asleep and then roll him over onto his back. now that definitely doesn't work since he's got full range of the head. so does anyone know any solutions? oh also he's 3 months on the 6th. I don't want to keep nursing him to sleep if I don't have to because I don't want him to need it when I go back to work in December. just need some ideas and tips.. thank you in advance! oh and here is a picture of my little one. ❤😍
