Solids at 4 months

Any of your babies having solids yet? If so, how much and how many times a day? My baby has really bad reflux and pediatrician recommended some cereal to make it thicker which was helped, but now she wants us to make it even thicker for a feeding (lunch time) and start getting him used to it and eat with a spoon so he can start veggies at 5 months. I would appreciate some advise!

Also, I know the starting solids before 6 months it’s a hot debate. AGAIN, as a mother , you have to weigh the pros and cons. Babies with horrible reflux need a different approach than other babies so please be respectful.
