I go to work at 7.20am every morning. When my boy was around 6mths old, I only reached hom at 7.30pm everyday. Once home I had to express milk, latch him, bathe, eat. Then play with him.
Thankfully he does not wake up in the middle of the night. Even if he does, my husband & maid will take care cos I need to wake up very early in the morning.
It was quite tiring but I got used to it after a while
