Hi Sejal, how old is our LO now ? For me, I wouldnt walk away. As my DS had a nursing to sleep association, so he would scream and cry so badly by the time I put him on his crib. So at the beginning, I would pat his bump around 5-10 minutes. At that time he would screamed. If it gets escalate ( real emotional cry ), I would pick him up, pat his back until he is quite calm. If it has been 1 minute since I picked him up but he hasnt stop crying, I would put him down to his crib, and pick him up again. Do you think you pick your LO too often or during mantra cry and hold him too long ?
