Have you guys adjusted back from the time difference? There is also an 18m regression? I’m sorry, I don’t have any advice, but if all else fails I have a fantastic sleep consultant that will be able to help you
check out the sleepy little bubs on instagram - they might be able to help
There is an 18 month regression. We just went through it! Hope it gets better for you
My son is at this stage we were legit up and down last night as he would be asleep I would walk out and he would cry again, really breaks your heart because you just don’t know what they need
My 17 month old started doing the same thing randomly. She would finish her bottle then spend the next half an hour trying to escape the room. I put it down to a growth stage. I ended up giving her much more milk before bed and it settled her. Maybe he's growing and finishes the bottle and is still hungry?
