Things will only get better. I started to go back to work when my son was 3 months old. At that time, he would still wake up 2-3 times in the middle of the night. I had a maid helping me but I didn't trust her so I prefered to do that myself. My husband would sleep till morning and he wouldn't wake up and help with whatsoever. If I could do it, you can do that too. By 4 months, my boy only woke up one time at 4am. By 6 months, he slept through the night. Hang in there!
