First of all, thanks to everyone contributing to this website. Where I live, it's almost impossible to find a decent lactation consultant and LLL has been a life saver.
Now to my problem. My daughter was born weighing 3.5 kg on the 50th centile. She's exclusively breastfed and was gaining well for 2.5 months, always on the 50th centile.
At the age of 2.5 months she suffered from diarrhea and since then has been having problems gaining weight.
At 3 months she weighed only 5.4 kg. After 1 month she gained only 100 grams and she's on the 9th centile now. She's latching well and swallowing. She poops 2-3 times a day and wets her diaper 6-7 times.
When she's awake, she laughs and plays, but gets frequently fussy and only naps very occasionaly for 30 minutes or so. At night, she wakes up every 2-3 hours to feed (before, she used to sleep for 4-5 hours straight)
Her pediatrician was very concerned at her 4 month check up (5.5 kg) and strongly suggested I supplement with formula. We agreed to give it 2 more weeks of exclusive breasfeeding if I pump frequently during the day and bottle feed her the hind milk at night. I've been pumping 3-4 times a day and getting 1-2 oz each pumping session so it's not like I have a supply problem.
it's only been a week since her 4 month check up but she hasn't gained any weight. I feel guilty insisting on breasfeeding her exclusively because I don't know if it's harming her as she's not gaining weight. Her length is still between the 25th and 50th percentile so I'm hoping she's just naturally thin. But my pediatrician insists she needs supplementation or her development will suffer and I'm at a loss. Her appointment is in a week and if she doesn't gain any weight by then then I think I'll have to start supplementing with formula.
Anyone had a similar experience? Did you end up supplementing? Any help would be appreciated
