Help cluster feeding!!

Hannah🇬🇧

My baby is 4 days old and for the past 2 days she is feeding non stop but mainly through the night. But she has also fed nearly all day today aswell!! Is that cluster feeding and normal? I though they just did it for a certain part of day. But she has literally fed all last night and all today with no sign of it calming down. Is there anything I could be doing? I have a pump and dummies/pacifiers ready but have not yet used them. Feel like I’m guna go crazy from lack of sleep. I also have a 5 year old who needs my attention but I didn’t BF him as he wouldn’t latch and I gave up quickly. I really want to BF this time as she latches on well for the most part.
