shell - thanks for your wonderful supportive message
i got him weighed today and he put on 400g in 2 weeks and grew 2cm. must be a 3mth growth spurt. he's in the 5th percentile, moved from 3rd, he's still tiny but i have to remember he was 2 weeks early. im still glad cos he only put on 150g over 2 weeks over last weigh in. Although it's only the 5th percentile in height and weight, im really happy.:dance::hooray: I'm going to continue with the formula top up.
shell - sorry about having to top up and express. i was expressing, bf-ing and then topping up in the early days and i was getting so little sleep. it's really hard work. i hope it's only for a short while.
