4.5 month old is getting worse and worse, waking either every time he is put down or 10 minutes later or if I'm lucky 45 minutes later, for the last 4-5 weeks. Even if he's had a bottle of formula (he is predominantly breastfeeding) he doesn't settle so I suspect it's habit rather than hunger. Basically I'm wondering if the pick up put down method might work as currently I'm jiggling/cuddling him to sleep 10+ times a night with little success/sleep for myself. If he cries my toddler wakes. Husband tries to help but has a job where he needs a reasonable amount of sleep and baby is sleeping in our room in a crib until 6 months. Co-sleeping is not something I would want to do. Thank you
