Hi nicky I'm reading this with interest as feel i may be advised to top up when DS is weighed later today.
He is 3 wks old today.
Birth weight 9lb 1 4.1kg
Day 5 had lost 200g
Day 10 had gained 40g
Day 17 had lost 80g
So has ultimately lost weight. I have had a variety of conflicting advice and been very upset about this. DS does however look very healthy, pink, alert and is a busy active baby and strong too.
I was advised on Monday to switch feed, so 5 minutes one side then change to other, carry on until he's finished. If he falls asleep try to rouse him, strip him down and change nappy if need be. Also if he seems to be suckling but not swallowing, do breast compressions to get the milk in his mouth (look on YouTube, basically hand express into his mouth)
I have been doing all this and really hope he has gained a bit today. I don't want to top up with formula.
He is having plenty of wet/dirty nappies.
He was also feeding a LOT which i think is why i was so surprised at him losing weight. But looking back i think he was comfort sucking a lot and not getting much milk in. Two days of following the advice above and i have noticed a difference in how he feeds (hopefully not wishful thinking)
Might be worth a trying the same til your next weigh in? I'll report back after mine later.
