Help! my Kitten has diarrhea

Thanks for replying, I changed his diet yesterday at the morning, i bought evaporated goat milk can from Kroger, i dilute 1 part milk to 1 part water, i also add half teaspoon of KAro syrup ( a vet recommended to me because he was constipated), he was fine before, he started the diarrhea today in the afternoon, so i guess its because the change of diet, i was thinking maybe if feed him more often small quantities of KMR formula but dilute with more water ( 1 part milk to 3 part of water) i don’t know if that would help him, what do you think?. I was feeding him with KMR since i found him, but he was constipated, i took him to the vet, and she said that KMR is the best brand that he will be fine after a enema and she also told me that if he can’t poop i can give him a enema at home, i did it twice. Im sorry im new in this, where i can get pedyalite?

I don’t understand why the vet recommend karo syrup, my kitten wasn’t lethargic, he was fine, playful and always wanted to eat, i was looking online and there is not connection between kart syrup and constipation. Thank you so much i will check them now. i will continue with goat milk, i really appreciate your help.

I don’t trust in that vet anymore, i specified her that my kitten was fine, happy and playful. His diarrhea started today after lunch, definitely he is pooping more than normal because in the past he was constipated, he pooped maybe 5 times today, the first time it was a big quantity, the rest was very small quantity. About the constipation i tried so many things before going to the vet, i tried the triangle method, i tried putting a thermometer with vaseline and also stimulate with a wet clothe, i tried so many things without success. I went to the vet and with the enema he finally pooped, the vet gave me enema for do it at home, only with that i could make him poop,but i don’t use it everyday, i wait 3 days for use the enema, i’ve never had a kitten before, all is new for me, i didn’t know how complicated is it, i only hope i can do everything correctly, i don’t want he is constipated or with diarrhea, i only hope he can poop normal someday :(. i don’t wanna use the enema anymore, but i don’t know what more to do, for that i tried with the goat milk, i read so many great things about it, i really have the hope it can help to my baby boy. he is 3 weeks and half now (guessing) i was feeding him every 4 hours, do you think i should continue or i should feed him in different timeframe?
Thank you for the reply, i was so sad and desperate,i feel better now that i know what i can do.I definitely let you know how is he doing.
