If he's not losing weight then i wouldn't worry and if he's doing nearly everything at the right again then don't worry.

Kimberley was born weighing 2.216kilos and is now 3.5yrs old and a very fussy eater won't eat much at all. She now weighs 16.6kilos and is 91cm tall.

Alexander was born weighing 2.660kilos and is lactose intolerant but he's always managed to put the weight on well. But he eats a little better than kimberley does.

Has your MCH not booked you in to see a dietition to talk about what other things you can try.

Would he be able to have rice milk ? Not sure what is in that but it might be worth a look. What about any of the lactose free products you can buy ?
