How do we (4-month-old) get back in the groove after her first cold?

My 4-month-old battled her first cold last week (holy moly - that was rough. Why did I not know it would be that rough.) and sleep has been pretty terrible since. Now that’s she’s better, she’s still waking up every 1-2 hours at night. Before cold, she slept from 7:30-4 every night. How do we get back into her old sleep routine?? Kinda feel like I’m going insane with so many days without sleep... via /r/Parenting https://ift.tt/2HXqiid
