i was still latching my son when i return to work on his 4th month and this continues for another 2 mths. When i wean him off, i just give him bottle instead of my breast. When i latch on, he woke up every 3hrly during the night even after we give him bottle. Only when we started to train him by giving water then now, he either wake up around 1-2am then sleep thru to 5-6am or he will sleep thru and only wake up around 5-6 am. His sleeping time is 8.30pm the max, he cannot last till after that.
