Baby girl is 4 months old and heavy. Nurse wants me to reduce feeds.

EDIT; Saw her GP today and she said she’s fine. The concern was going up 25% in 8 weeks but she’s healthy and the doctor said keep feeding her when she’s hungry! Thanks for all your comments and support that I’m doing the right thing 😋 🥛

As the title says, my daughter is 18 weeks old and 15 weeks corrected age. She’s 7kilos and put on 2kg in 8 weeks since her last nurse check up. The nurse was very very shocked at her weight gain and said no more scheduled feeding rather demand feeding and omit the overnight feed. Not sure how I feel about it. I’d love to wean her from the overnight feed and get more sleep but she’s genuinely hungry and sucks on her dummy so hard that it leaves an imprint on her face if I don’t feed her. She’s 75th percentile for weight and height. She’s very long and a little chubby but certainly not fat. She has arm and leg rolls that you just want to bite when you see them 😂 Re the demand feeding, she gets 1 bottle (either breast or formula as we mix feed) of 165ml in her wake window so although it’s a scheduled feed, I’m not going to let her go hungry in her wake window. So I’m not sure what to do? Do I try and wean the overnight feed? Or omit a day feed? It feels wrong putting her on a diet!
