hi, i did DF from the very beginning. my baby is now 4m1w old. around 3m he was waking at 2-3 to eat and sometimes at 4-5. i did not bother much about it, but closer to 4 months, he started to wake up only once, and when he woke up more times, i'd use pu/pd to get him back t sleep.
for a few nights, i would wake up, at 3, or 4, or 5 AM, and have my breasts leaking and i was confused/worried that my baby has not woke up, i was picking him up and breastfeeding. but then, in the morning he would not eat as he should... last night, we had a harder time going to sleep, he ate at 6.30 then 8pm and fell asleep at 10pm. so, i decided to skip the DF... he slept until 6AM...
so i guess, there is good news for me, that my baby is ready to sleep all night, and yes, dreamfeed really works, just keep on a little longer
