DD is 10 months old and has been prescribed penicillin for a chest infection, dosed 3 times per day to be given at regular intervals. DH seems to think this means strictly 8 hourly, and we should wake her on the middle of the night. I think you have one on waking one at bedtime and one in the middle of the day. DD is not well and needs all the sleep she can get, especially as she's still coughing herself awake. Who's right?
