Milk issue

Shaqoria

So my daughter who I s about to be 1 years old on May 14 has been on Soy since she was about 3 or 4 months and was given medicine for her acid reflux(also she cannot drink any other brand than enfamil)...she has been taken off the acid reflux medicine and has been doing great without it...however she has still been on the soy milk and no store near me or in a 2 hour drive sales the toddler soy me and my husband have looked in Walmart,target etc no toddler soy...I also notice that the toddler soy is only good for ages 9-18 months should I let her try the enfamil toddler next step to see if she has grew out of the soy milk stage...I’ve been calling and messaging her doctor and still haven’t received a call or message back and I continue to repeat same steps of contacting and it’s been 4 months
