Hi ladies, my son turned 17 weeks today when some people advise baby rice but I've read a few things on google and people are saying no wait till 6 months my son is on 9 ounces every 4 hours and constantly watches everything I'm eating his really good with holding his head up and I definitely think his ready, is there any other moms out there who have started weaning? Thanks
