Talk to Pediatrician on Baby Vomit

My baby is now 6 months +1week old. Maine usko solid food dena start kardiya hai like cerelac mashed banana and soji. He takes his feeder 3 times and cerelac and at one day apple puree and other day is mashed bananas. My concern is he vomits. Kabhi bht ziyada karega or kabhi kam. Lekin jab bhi vomit karta hai to phata howa dhood nikalta hai uske sath puree bhi nikal deta hai. Kabhi zyada vomit kardeta hai or kabui kam lekin jab bhi karega us main phata howa milk nikale ga. Baqi uska weight birth se double hai or active bhi hai infact main uska weight heck karti rehti ho to wo barh hi raha hai lekin vomit karna normal hai kiya?? Main puree k allawa or kya dey sakti ho? One more thing he is also on motherfeed. Like kabhi bhi din main ya raat main on demand ise motherfeed milti rehti hai.
