Just found a fab Tiktok quote:
"You know sumpin'? It doesn't matter
The guidance about timings is ok, but honestly, if you switch sooner or later, it really won't matter in the longer term.
The thing about 30 mins to 'reach' the hindmilk is based on a misunderstanding, and I don't understand why more than 45 mins is a no-no. Baby sorts out foremilk and hindmilk, and timing is unnecessary
In the early days, as long as each side is roughly stimulated the same, you'll be ok. With more established bf, it matters much less, and many babies have a fave breast they use more."
(From this thread about when to switch sides, if you want to put it in context.)
I really wish someone had told me that in the early days! I never used to know whether DS was done with a side or whether he was fussing
