I have a 6 month old and we started to sleep train him 2 weeks ago. He was a Velcro baby. They say to put them in the cot half asleep and then rub/pat/Sing to them. Try not to pick them up again. The first couple of days are hard work but it gets easier and baby learns really quickly! I adapted the ferber method, to work for us. ‘The happy song’ is my life saver Good luck x
White noise has always helped my little one, may be ideal to try the technique where you keep contact with her after you lay her down. So you would keep your hand on her chest lightly so she knows you're still there, rock gently side to side if needed and once you think she has settled slowly remove your hand and back away quietly. 😊
I swaddle then unswaddle after a few minutes when they in the cot. Also noticed I made the mattress thicker so it was more comfy when she lays on it
