Hiya. I have a gadget called an owlet that measures my daughters sleep. Despite the fact that she's in bed 7.30on and wakes at 6.30am, and has 2x 1 or 1.5 hour naps, she only manages between 12-13 hours sleep a day. I've seen in some places it say she needs minimum 14, some places even say 16!
She is quite cranky a lot of the time and I wonder if this is to do with this. I just don't know how to make her sleep more! She has white noise, eats and drinks well, blackout blinds and a quiet house.
