Help me get my 4 month old to nap on her own!!!

For the past few weeks I've been letting my daughter nap on me in her carrier.. it's time to get her to sleep on her own!! I just don't know how!! I've tried to rock her and lay her down and putting her to sleep sleepy but awake but she sleeps for 20 min or less and wakes up!! Within a 6 hour time period she's slept maybe 30 min total after several rounds of rocking and calming and laying her down!!! I'm just so close to giving up and wearing her so she can sleep! Then she becomes over tired cause she's only slept 30 mins within a 6hr period!! I don't wanna let her CIO at this young age! I just don't know what else to do!!! She's EBF but I know she's not waking cause she's hungry but cause she wants her momma!!
