2 years and 5 months here. He never slept well, wakes up during the night, makes all sorts of sounds while sleeping, and wakes up early (5~6 am). Doctor said some kids are like this and it may get better over the years. The lack of sleep took a lot of my concentration, energy, and memory.
Same here. 3.5 year old and one year old twins. Poor sleep and just general fatigue most days. It’s hard to convey to those who sleep well how challenging it is to be constantly sleep deprived.
