Hi there, 1-3 months total sleep is 15-18 hours in a 24 hour period, three naps of 1.5 hours each + catnap; 8 hours at night (still waking for feeds). 5:30 - 8:30 is part of the time known as the 'witching hour' and many babies are unsettled in early evening. It's very normal, peaks at 6 - 8 weeks...usually settles by 12 weeks. Holding and swaddling are pretty much what normally works, also using a baby carrier/sling, pushing in the pram/stroller, taking for a drive, rocking in a cradle, using a swing, bouncing on a ball...I am sure I have left something out...oh yeah putting LO in the bath, using white noise (running hairdryer, vacuum, bathroom fan)...basically whatever works to calm your LO.
