DS (he's 4.5 months) will 9 out of 10 times wake up during transfer from my arms to his crib. It's like he knows! It's not even a fussy wake. It's a full on wail. So it's a rinse and repeat process (nurse to calm, pop off boob, put back down). However, if I transfer him from my arms to our bed, he stays asleep!! What the... I don't sleep next to him. Just lay him down and move away. Given he doesn't stay asleep for long, but still. Not sure what's the difference! How do you keep your LO asleep during transfer?
