Ok I have had my babies on a 18/6 light cycle for about a week now and last night forgot to turn off the lights and turned them off around 2 and half hours later but continued with the 18/6 light cycle, do I need to continue my light cycle 18/6 as I did before from midnight until 8 in the morning or keep it as it is now? from 2 in the morning until 10 in the morning? babies are about 2 and half weeks old now, going on 3
