Sorry this is long...
Doctor blames it all on his cold which became a very mild chest infection. Ditto HV kept saying 'you dont have breastfeeding problem'.
It went like this:
Wednesday last week - had his check, getting over cold (which had lasted 10 days)
Monday this week - I still felt feeding wasn't working so I went to the lactation clinic - they said feeding looked totally fine but that he was very underweight and suggested expressing to give top ups.
Tuesday - HV worried about weight and doc listened to his chest - found a 'crackle' which he said was infection post-cold and put him on antibiotics. But DS had no cough, no snuffly nose, no fever, was bright and bouncy... frankly, he didn't look ill at all.
He also had his immunisations that day on their advice.
He was then fussy and very hungry all week (I know fussiness normal after jabs). Gulped down food. Even with me feeding 6-8 times a day the pumping and giving him EMB top ups he's still hungry all the time hence formula... I'm feeding him every 2-3 hours then I express what I can and use that next feed to top up if needed (almost always is).
Basically I spent this week shoving every bit of milk I could into him to get his weight up. Eg yesterday - 7 feeds + topups totaling 1300ml!
Friday - doc said 'crackle' gone. We asked for referral for snip and he wasn't keen but we pushed the point and he agreed.
Doc reckons he's now feeding heaps because he's getting over the infection. But he just often doesn't seem to get satisfied after I BF. He has done in the past, but it's hard and takes forever (at least an hour). He's much less grouchy since I started topping up so much.
. I think we'll just get him snipped and I've contacted a lactation consultation. I just don't understand why the doctor is against it. We had actually asked weks ago when he struggled hugely to regain his birth weight (only achieved that by expressing and topping up like mad).
Sorry that was so long. thanks for comments, esp beachavendrea - that's very helpful to know about your experience.
