The main reason people don’t breastfeed is misinformation.
you don’t have to feed a baby to bond with it.
introducing a bottle too soon can lead to bottle preference, and affect establishing a supply.
pumping is 3x the work. It doesn’t help to increase supply as much as breastfeeding does. Psychologically it can be detrimental as many women can’t express leading them to think they have no milk. To keep up supply if you bottle feed you should pump at the same time to maintain supply, you might as well just feed. No point someone else feeding while you faff round pumping- 2 people to do one persons job.
night feeds release hormones that increase supply. Many people express or give bottles at night, this can affect supply detrimentally. Stick with night feeding and ask your “helpful” person to watch the baby another time so you can catch up on sleep. A night feed is often wake feed sleep- a night bottle is much more faff, you wake anyway, and now you’re missing a vital night feed which increases supply.
you don’t have to introduce a bottle. Combi feeding ime is twice the work, and can mean you affect your supply. My second I told everyone to fuck off with the “advice” about needing to give bottles or it would be too hard for me, I’d never be able to leave them etc. utter bollocks. We were properly in the swing by 3 months so I could take short breaks, by 6 they were weaning and I could leave them for longer periods and feed when I got back. 7 months I went back to work, nursery gave solids and cup drinks, I fed around that. Much, much easier.
oh and my top tip- and that of my HV, you don’t have to get them weighed. If all markers are normal and you have no concerns, weeing, pooing, sleeping well etc then don’t bother. It’s just an extra level of stress as most hcp are used to formula weight gain and start advising top ups, pumping, strict regimes etc to keep up with ff weight gain instead of just feeding as much as possible.
bf is all on you, and people will frame it as only doing it to help. It doesn’t.
