My newborn doesn't seem to have a sleep rhythm. Is this normal??

We are trying to adapt to new life with two. My son is actually doing great. I wanted to ask you about my 2 month old. He has bad colic. On Monday I started him on Pepcid. He would cry for hours. Now he is doing better but we still have the witching hour from 7-10. The routine I have with him for bed is: warm bath with lavender oil then bottle and he is supposed to go to sleep but he stays awake. He goes to sleep around 10pm, wakes to eat again at 12am-1am to then wake again at 4am then 6am and then 8am. The 6am feeding is breastfed. Then he gets a bottle during the day. He eats about 4-5oz every 2-3 hours. I feel like I can’t get on any type of schedule with him. My older son, at this age, had a schedule at least to eat. My newborn is all over the place I feel. Any advice?
