Sleep training

Cristina

My LO is 16 weeks and I’m about to go back to work in another 2 and right now he is incredibly hard to get to sleep unless nursed. He will take a bottle as we have tried on a few occasions but I’m super anxious he won’t get any rest while I’m working. I’m gonna be away about 10 hours a day. Any advice mamas?! Please help ease my mind.
