We did bls with dd and will bs with this bub too. We started at 5 months with dd....it's recommended that you wait until 6 months or the child is at least sitting unassisted. Showing animterest in food isn't enough. I know it might seem strange to delay starting solids as logically you think you'll be putting the baby behind but in all reality, blw/bls kids often end up eating much better, a wider variety and range of foods earlier on. My dd can use a fork and spoon at 16 months, will try all foods at least once and her general co-ordination for hand/eye seems to be advanced and I put this down to bls. I'm a big fan
