Small children

Those with little ones on the smaller size how do you cope with the comments and interference. My 16 month old was wandering around at rhyme time today (she's a confident walker but in size 6-9 months clothes, no hair, and 0-6 months pram shoe) and I let her wander and just watch and everyone's putting their arms out to help her and commenting how small she is and can't believe she's walking so young and telling all the other children (some are younger than her too) to be careful of the baby I'm getting fed up of always saying "she's a confident walker she's 16 months old now I'm watching her I know she's small but she's older than she looks" all that stuff people don't seem to listen
