Cluster feeding help

Danielle

My 2nd born is 1 week old and she seems to always want to eat from about 2pm-2am. She gives hunger cues every 45 minutes to an hour and a half during that time. If she’s not eating, she’s crying. I barely have been able to get sleep because as soon as I put her down she wakes up crying and putting her hands to her mouth/rooting. When I was in the hospital lactation said once my milk comes in the cluster feeding should stop, but this is going on day 6 of it and I’ve had my milk since day 3. Did anyone else experience this and how long did it last?
