Thank God for an answered prayer! I prayed that Jon could fall asleep without having to nurse to sleep, and to do so quietly without the wailing so that MIL can rest :) :) Jon did it!
Managed to notice him starting to be a bit cranky and wanting to sleep. So quickly brought him into the room, off all lights and closed the door so that there was completely no distractions or things that would alert him. Let him nurse for a while, and haha becos supply soooo low, poor Jon got a bit fed up with me and turned away. He then started getting cranky and I quickly made him 150ml FM. Let him drink quietly, and thereafter toss and turn in bed until he slept. Guess the trick is to remove all distractions in the room, let him toss n turn after a full feed and not talk to him. He will sleep after a while (max so far 30mins of tossing). Okie, he only drank 100ml but I'm cool with it becos I'll just heat and keep the FM for the next night feed.
Pray that Jon will continue to sleep well tonite! I'm so encouraged by tonite's outcome! :)
