Anyone else experience low supply in the afternoon?

[Cash02]

I have awful supply in the afternoon from about 3pm to 8pm. I’ve been breastfeeding for 7months, thought it would get better but it hasn’t, my DD gets very fussy because of this and the afternoons/bedtime is a struggle!
Anyone else have this issue and does anyone have any tips?

I know this is normal when you're baby is younger as you produce less prolactin in the late afternoon. I don't know if it's normal to continue as long as 7 months - maybe it is?
Could you just fill her up with solid food at that time but obviously continue to nurse her too?
Give her milky porridge before bed?
