You can start regular dairy milk if unavoidable

Detailed Answer:
Hi

Thanks for asking on this platform

I have gone through the query and do understand your concern.
As per recommendation dairy milk is to be started after completion of one year. It has been seen that chances of allergic disorders are more if dairy product started before one year of age.It is also seen that earlier is the age for introduction of dairy milk more is the risk.
This recommendation is based on several reaserch studies and depending on the results an age criteria of 12 months has been made. In these studies there were also cases of less than one year of age in whom there was no increase in allergic risk in future. So this means that all children with age less than one year of age will not develop this risk if regular milk is introduced earlier.
If unavoidable you can start dairy milk at 11 months of age without much risk.
I hope this helps.
Please let me know if you have any more doubts.
Regards
