Hi Maddylyn, i was BF my DD to sleep as well until she got to about 3months she is now 5months. I started doing the whole feed, play, sleep thing during the day as i realised i would feed her to sleep & put her down but she wasn't really tired. Now after i feed her she has a play & when i notice her tired signs i wrap her up & put her down. At first i would rock, pat & sing to her but now she goes down pretty well on her own as she is tired enough NO crying involved. It did take a few weeks to work though as my DD would get a bit upset as soon as she was wrapped as well but now she is used to it, she wouldn't take a dummy either. Sometimes she will have a bit of a talk & look around before she goes to sleep but she is generally asleep within 10mins. I still BF her to sleep at night though as she falls asleep on the boob so i just let her be & she sleeps through the night. I learnt i just had to be consistent with whatever i was doing & this works for me. I think you just do what you have to do & what works for you & if feeding her to sleep is working then i wouldn't change it, unless like you said it might cause problems if your not there.
Goodluck
