Sleepless nights

Here I am again up and wide awake at 1:49 am. I went to bed at around 9 pm with my little boy when I put him to bed. I didn't take him long to fall asleep so I stayed in bed until I fell asleep too. Then, I woke up for the need to go to the bathroom which usually happens every single night and then going back to sleep is a struggle as I lay in bed trying to fall asleep. Getting enough sleep at night is really hard for me ever since I have my baby because I have to wake up when he is up in the middle of the night for his milk. Although now that he is more than a year old he only wakes up once at night for his milk and goes back to sleep but I always have a hard time going back to sleep after I wake up. Tyler is even getting better at sleeping through the night coz he usually ask for milk around 4 or 5 in the morning and still goes back to sleep on his own but with my second pregnancy now sleepless nights will never go away I guess.
