I want to introduce a formula feed to my ds aged 23 weeks. He's a big healthy boy (75 centile) and has been sitting well for a month already, so seems older than he is.
Looking at the formula labels there seems to be this up-to-6 months milk, and follow-on for after 6 months. What's the difference and can I just start him with the follow-on a couple of weeks early, rather than getting him used to something and then changing over a week later?
This may be a silly question but i can't find the info anywhere and want some reassurance that the follow-on won't "hurt" him - living up to my nickname or what?
Thanks
