For the past while Harrison's been having his last bottle at 12am and then sleeping until about 8am. The past couple weeks I've had to wake him up to give him his last bottle and he hasn't been drinking it all because he's so tired. Last night he only drank 10ml! Would it be a good idea to give him his last bottle around 9-10pm before he usually falls asleep and let him sleep through the night? He's taking 6oz during the day xx
