I returned to work 2 weeks ago and ever since then my son stopped sleeping through the night. He is 3 months old and had been sleeping 10 hours at night (sometimes waking once). I work three 12 hours shifts each week and he is home with daddy. He eats every 3-4 hours with a morning and afternoon nap. The past 2 weeks he is sleeping only 4 hour stretches and then he wakes up every hour and will only go back to sleep on me. Will this just take time for him to adjust to me working? Any advice?
