In principle, yes but not absolute. Some babies eat more obviously and some babies just need a little bit more. I cannot recall my son had that (maybe because I did not know it before) but my daughter experienced growth perks, only ate more frequent for a few days.
FYI, growth perks happen at 3 weeks, 3 months, 6 months, 9 months, 12 months, usually obviously shown in the first 3 times.
