I usually arrived home around 5.30pm, 6pm if I need to go to the shop for food, then, prepare dinner and dinner start 7pm. We eat together! take a while for him to finish dinner, then he play a while, then, off to bed around 8pm or 8.15pm, spend around 25mins for sleep routine (last milk, brushteeth, change PJs, read book), he will fall to sleep before 9pm. Therefore, I can start to study after 9pm.
when I told my friend my baby go to bed around 8 or 8.15pm, they all said it's very early, but I think it's bit late. I want him go to bed around 7.30 but it's impossible because the schedule is already very tight.
Very 'LUCKY' that I don't need to wash dishes
As your baby is 1 year old, he/she should go to bed around 7, then, have a dream feed around 11pm. You should be able to study at night unless your baby doesn't have routine.
