so I have almost 5 month baby boy and he is very light sleeper. his naps is 20-40 min but during night he sleeps well. he goes to sleep whith bottle of milk. so he fussy all day coz he is not getting enough sleep. our pediatrician give us sleep training on which u will have crying baby. I don't use that coz me and my husband hats when babies r crying. is there any other method to help babies fall asleep on thier own? our pediatrician said if will sleep on his own then his naps will be longer. any tips any tricks?
