I recently saw my GP as my DD has had a tummy bug and he asked me if she had always been skinny as she looks a little underweight. He looked concerned and in all honesty it has been a concern of mine for a few months now.
She is 17 months old and weighs 8Kg. I have recently had a row with my DM because she has been hounding me about my daughter looking malnourished and it has made me feel even worse.
I exclusively breastfed my daughter on demand until she started eating solids but it has been a big struggle to get her to eat more solids and she still prefers breastfeeding to actual meals. I know she is hungry but she pushes aside or plays with her meals and then comes to me for milk.
She is allergic to dairy so I want to breastfeed until she is two and I give her oatmilk whenever I can, but getting her to actually eat her food is very difficult.
I was reading some information on Kellymom which states that this is quite normal in breastfeeding toddlers but I am struggling to get my daughter to eat three meals a day. Today she hasn't even had one actual meal! She threw most of her food on the floor and then would come to me for milk instead. Even sliced cucumber went on the floor 
Her dad and I were both very skinny but tall children and my MIL says that she looks like her dad at that age but I am still worried. She is 86cm tall which I think is quite tall but I am so worried as she was always bang on the 50th percentile as an infant when it came to her weight.
Any advice? I am so worried and quite upset at the thought that my daughter may be malnourished.
