DD15 said she is falling behind at school and thinking of started drinking coffee. I suggested to start with tea and get into a better routine, do more exercise, homework everyday, less screen time.
I don’t think she is sleeping enough hours for a teenager, between 7 and 8 on school days.
We have limited time on her phone at 9pm on school days, and wifi goes off at 10:30pm so she uses IPAD sometimes,
FYI. I didn’t grow up in the UK so only started drinking tea late in my adulthood, and coffee only this year (I am 52), one around lunch time, if I take it after 2 it does impact my sleep.
