Trying to let Travis kinda fuss it out now when he's trying to go to sleep. When I first put him down he fussed for 5 mins then passed out. He just woke up and had a bottle. When I put him back in his bassinet he was whining but I just let him go and he's now back asleep (I think). He keeps making noises here and there but it's time for him to learn to fall back asleep without a bottle in his mouth. And in his own bed. And he won't take pacifiers so can't put those in his mouth. He knows the difference. Gonna try and do this for a few nights so hopefully nights start getting easier. I feel like he's still a newborn instead of 6 months
