I went back to work at 8 weeks. From 8 weeks to 5 months ds slept through the night. Last nursing was at 11pm and ds didn't wake again till 5-6 am. At month 5 he started waking 6-8 times a night to nurse. By the time he is back to sleeping a long stretch it is 7am and I am getting ready for work while he is snoring. I am so exhausted I can barely function all day at work and then come home to an infant and 3 teenagers. What can i do?? Advice please!
