Laila is still in 0000

She was fine for about 4 hours then just cracked it and was hysterical, DP had a shower with her and got her to sleep then i took over and she slept for a few hours then woke at 6:30pm in hysterics again so i gave her a little panadol and a feed and she went back to sleep. If the panadol knocks her out should i wake her for feeds or let her sleep? I dont think shes fed enough this afternoon IMO
