@felipeoliveir It takes time. If you want to really try SWAP, commit to at least 2 weeks of implementing the change to see if it's working. If you want success in a shorter timeframe then I'm sorry, but that's really only going to work with CIO, Ferber, or similar approaches.
I've copied in a comment I made to a different post here from a while back, to give you an idea of what to expect with SWAP:
Try to fade gradually over time (we did this for bedtime). Start with holding and rock all the way to sleep if that's where she is now. After she's settled, hold and sit for 8 minutes minimum, or until deeply asleep, then place in cot on side, bum first, roll her out of your grip smoothly (may have to practise awake, and watch some videos about transfer techniques). Then over 3-4 nights, reduce length of time rocking, and just sit still and pat while holding her until she's asleep. She will probably take longer to settle when you make this switch, but if she's tired enough and your wake windows are right for her age, then she will eventually fall asleep without being rocked. Then reduce the time holding each night by a few minutes. Once she's down to 5 minutes being held, the next night try laying her down on her side (or equivalent to however you hold her in your arms) and holding her down gently with one hand for pressure, and patting her with the other. Might take 20 minutes or more, but she will eventually fall asleep. It might not even work for the first night, in which case after 20 of fussing (or as long as you can handle) pick up and and pat in your arms until asleep, but no rocking or feeding. Try again the next night. There will come a night when she is tired enough to fall asleep while being patted. Then you reduce the time patting (I sing a song as well, and used that to track how long, ie how many choruses) until it's your desired length. My end point for this stage of sleep training was 1 minute of pats while singing a song, then fading the pats and song and walk out the room. If she's still awake but just fussing, let her be. Try to leave the room and see what happens. If she starts getting more upset, go in, but just pats. Leave once settled. Repeat until asleep.
...
My advice: make a plan for what you want to change, how many days to commit to, what the stages will be, and then each night write notes for what happened. And remember, up to 20 minutes of crying is still considered success (according to PLS) some babies just need to cry out a bit of energy at the end of the day.
Tracking how we went over time really helped me to see the progress, because every bedtime felt like it took forever, but for my bub, she actually learned the above steps in about 10 days (7 months old at the time). That was after 2 weeks of weaning off feeding to sleep (to go from feeding, to rocking only until she was fully sleep in my arms, yes it took 2 weeks). So in the space of 3.5 weeks she went from feeding to sleep every night and every nap being a contact nap, to completely independent sleep, day and night.
Now 7 months later, she's 14 months old and she's still going great. I put her down, pat and sing, she's still awake when I leave the room, cries for about 2-5 minutes, then goes to sleep. Some days are worse when she has a tooth coming, but generally she's asleep within 10 minutes. It's amazing, and it was a hard few weeks, but it was absolutely worth it!
