Excl pumping wanting to excl breastfeed help plz

Hi everyone I need some help. Little one has been exclusively drinking pumped breast milk for 5 weeks. Baby sometimes drinks from a nipple shield but he doesn't like it very much. I have also tried to put him on my breast but my nipples are a little flat (use to be inverted 5 weeks ago!) and he doesn't open his mouth wife enough or stay on. But for a minute on and off he will suck. I don't have milk supply issues though I wonder if the let down is too full on for him.

My lactation consultant told me to get him to suck on my nipple shield for 15-20 mins each feed but I found doing it made his feed almost an hour long and with the need to pump as well took me almost 2 hours to do one feeding. By then I had to feed again or had to feed earlier and pumping was missed out. My milk went down as I tried this for a few days. To be honest I was too tired to continue doing it and went back to just pumping and feeding.

Now that I have a better handle on motherhood I wanted to do try again but I don't want to go through weening off a nipple shield. If rather go from bottle fed exclusively to breast fed exclusively.

Anyone know how best to do this or if there's a way to do this?

I'm dying to get this sorted as I have to return my rented pump next week. I originally was going to stop breast milk and go straight to formulae when this happened. But I really want to give it another go. I'd love to breastfeed if I could for as long as possible I no longer want to go to formula.

Please help!

Try plunket, I went to their family centre in north shore (sure they should have something similar in other places as well) and you stay there for the morning/afternoon and the nurses/lactation consultant will help you with each feed. They also help you to get baby to nap etc so it is a casual day where you just focus on feeding your baby. I went two times and it really helped a lot.
