Underweight toddler

[mom16520]

Hello .
I am very stressed out. My 14 months old girl is only weight 6.2 kg. She was born full term and was 2.5 kg at birth.
She was exclusively on breastfeed. From starting she is not gaining weight much. After googling and all research and seeing the children same as her age I am very worried about her health.
Although I have started solid food when she was 6 months. And also she is very active. Plus started walking and having two teeth.
I am very worried about her.
Everyone is saying ' she is so small' and ' looks like 6 months old' etc.
Please help me. What should I do? I changed three ped . All three are saying as long as she is active there is no problem. Also they prescribed some vitamins which I am giving to her.
But still I can't help myself stressing out. Because she looks too small. Should I go for any tests? It could be any underlying decease? Please help me out. Waiting for your answers and reassurances.

Are you in the UK? She's well below the 0.4th centile and has dropped over a centile space from her relatively low birth weight, both of which would generally trigger some investigation. Have the paediatricians done a physical exam? Bloods? Considered a referral to a paediatric dietician or speech and language therapist (they often deal with feeding difficulties as well)?

Now that she is 14 months, how is she with solid food? What does she like to eat? Does she eat a good range of flavours and textures? I see on your other thread you say she is not a very good eater – in what way, just small quantities or something else? If it is quantity, you could consider letting her graze a bit, have relatively tidy food (small crackers, pieces of cheese, and so on) available basically whenever she wants to hopefully get some extra calories in. You could also try to make sure what she does eat is fairly high calorie, although I'm a bit more cautious about giving advice here as I'm not a dietician. Full fat dairy, certainly, and a generous hand with the butter/oil/cream for her meals. I think too many wholewheat products can also fill up babies and toddler before they've eaten enough calories, although there are obviously also some benefits to wholemeal things.
