my b also not falls asleep when she's about 2 months, but the situation improves after 3 months. i have tried various methods but in vain. i remember by that time, she would sleep long hours after always awake in daytime for a few days. i guess it is due to the reason that she has not get rid of "night milk", and the feeding time in daytime is not regular. however, she slightly establishs the pattern of sleep when i help her get rid of night milk. Now, she is nearly 7 months and she can sleep through the night for 9 hours la. Add oil and the situation will improve soon!
