What time is/was bedtime for your 3 month old?
DS's bed time has been gradually getting earlier 9:30, 9, 8:30 and the last couple of nights 8pm. He has been getting more difficult to put to sleep and has been doing some major crying in the evenings. I know he is overtired - he's been taking pretty short naps (30-45min) - is his bed time too late? Or is he just not napping enough?
