Day night confusion? ☀️

Claire • Proud mummy to baby Girl ❤️
My six week old baby is a delight during the day. Content sleepy happy .. Even hard to wake up .. Overnight is the opposite she can be fussy, feeds more regually,difficult to settle,has worse gas.. Doesn't like to sleep and wakes easily when she is asleep. 
Trying to keep it light in the day and not be as fun at night...
Has anyone got any tips or has anyone had something similar and seen a change around 6-8 weeks..?!! Please reply if you have id love some positive news! Thanks
