Breastfeeding with nipple shields long-term

Michelle

I started using a nipple shield at around 6 days post birth and still doing so at 4 weeks. I have soft nipples and baby struggles to latch without the shields. Feedings are going well and we do the occasional top-up with formula. However lactation nurse has advised we ditch the shields for better and shorter feeds (currently feeds take about 40 mins). Anyone using shields long-term and feeding with succes?
