Can I ask how much food your bf 12-13 month old is eating?
Dd is still very much in the boob. She started solids late at 8 months due to total disinterest from her, but blw was gong ok not she hasn't really increased the amount she eats. It's just handfuls here and there, few spoons of this and that. She seems to enjoy playing with the food and she will try anything but she does mostly fill up on milk. I have tried offering food when she has had no milk for a few hours, and she's the same. My boys were nothing like this they ate loads!
