I can't deal with these people saying you'll fail if you take formula. Combination feeding is a thing and it means that lots of babies get breast milk when their mothers otherwise wouldn't or couldn't ebf. Read into it
No, it doesn’t necessarily mean bf will fail.
However it can interfere with getting bf established, and if combination feeding doesn’t work for you, it is almost impossible to go back to fully bf. If the o/p is determined to bf, best way to to it is bf as much as possible.
If you are struggling to bf and combi feeding helps prolong bf, then that is fab, as you say. But for someone who does want to bf, there is a risk. It is up to that mother whether the risk to bf is worth it.
I am someone who learned the hard way- i was persuaded to give formula for the usual reasons, others wanted to feed, baby would sleep better, i’d get a break etc. But it developed into a cycle where baby would fight the breast more after each bottle, so we’d give formula to settle, they’d fight the breast, then i had less milk so increased formula. Slide to completely ff took about 2 weeks.
With my second i stuck to my guns and bf only. It was far far easier to ride out any rough patches and i bf long term.
So i would say if bf means a lot to you, stick with bf as much as possible. If you aren’t overly worried, give combi feeding a go. It might work, if it doesn’t, ff.
