How concerning is it for a 1 year old to lose weight?

[iwasagirlinavillage]

DD2 is 13 months old, born at 33 weeks. She was born on the 50th centile and has had slow weight gain. We saw her consultant yesterday and she has lost weight. She weighs 7.4kg and is on the 2nd centile. She is 95g lighter than she was 1 month ago and when she was weighed a month ago she had dropped down from the 9th to the second centile. The weights were taken and recorded in different places - May was at the clinic and on the weight chart. June was her 1 yr review and not plotted, yesterday it was done by her consultant and plotted on the chart in her notes - so I'm not sure if anyone has made the connection. She is weaned and still breastfed. She has grown in length over this time. Her consultant has ordered a lot of blood tests as she has had repeated infections since October. I'm wondering how concerned I should be about this. I should have asked her consultant but I was more focused on making sure I told her all of the relevant information. I'm going to take her to the clinic in a few weeks and see how her weight is then.

monitor on exactly same scales, scales can be out.
you say The weights were taken and recorded in different places - - so it is not an accurate record.
go back to same place every month for next three months then review.
record food and fluid intake for a week and see local dietitian to review calorie intake

Hi village
Is it calories in that's the problem? If so then being constantly ill might just be the reason for this?
If she's eating and drinking well and she's still not putting on weight then that's more worrying - if you can't account for the weight loss/static
Has she just started walking? Might be burning off more calories?
Basically I wouldn't worry about the weight alone - it's what causing it that's the concern and sounds like your consultant is on top of.
