Switching from Enfamil Gentlease to Goats milk formula?

My son had severe reflux since birth & is still very sensitive when it comes to foods. I feel he is behind on table foods because of his reflux. He’s tall & skinny for his age since he’s crawling more his reflux has subsided greatly thank god. Anyways his 1st birthday is coming up & I’ve been thinking of transition alternatives after some reading I’m going to discuss with his pediatrician about Goats Milk with all the belly issues he’s had I think it’s the best option. I just worry about his weight I want to make sure he’s getting everything he needs nutritionally from what he’s drinking..since he still isn’t keen on eating all table foods. Anyways anyone try these? Opinions?
