So to update, Evan was weighed today and we have only gained 2oz in 10 days despite feeding at least 10 times per day. He is 11 weeks tomorrow and weighs 9lb 4oz. My LC was very helpful and told me to carry on as we are but try to get more rest and stop weighing him so often - she suggested in a month! She confirmed he latched and feeds well and suggested that his lack of sleep/naps could just mean he is a more alert baby (I agree he is very alert) and try not to worry.
I just wondered if anyone else has any advice please. I feel relaxed now but the slow gain does concern me.
