Baby won't sleep unless on boob help.

Nicole • Was pregnant last year, missed it so much got prego again!!! . Social worker for the homeless. I have a infant and 4 dogs 🐶🐶🐶🐶 Second pregnancy a year later 😯
He is one month old and use to sleep in his bassinet- now he cries non stop unless he is on boob and sleeping on me. If I lay him down he wakes up within 5 min.. Does this mean he is not getting enough milk?
