Of course being flexible is important, and this is something that I have mentioned several times already. BLW is not anything precious or special, it's just a method of feeding a baby! Often other people seem to project the idea that people who do it are inflexible and dogmatic, and on this thread there has been the implication that they also put the wellbeing of their baby second. That sort of insinuation irritates me intensely.
Egg, you said you were sad to see people "push their agenda" in an earlier post. That's what I was responding to, so I am not inventing things or projecting. The OP hasn't been showing a blind determination to pursue a fixed course. In a recent post she clearly said that she would continue with BLW until the next weigh in (which is monthly) and then switch to finger foods plus purees if her daughter's weight gain slows too much or stalls. That sounds very sensible and flexible to me.
Highlow, I think that one of the good points of BLW is not knowing the exact volume of x, y, z that your baby is eating. Just like when you breastfeed, you have no idea how much milk they're taking. I appreciate you will probably think that makes me dangerously negligent! The idea is that you offer balanced meals across the week or so, and they take what they want. Sometimes they go for one type of food more than another, but it balances out over a week or two.
I don't understand your last sentence at all, HighLow. When I cook for my baby I do exactly the same as you. It's just that I cook enough for everyone, and call it a family meal. Baby gets some alongside everyone else. It's not just random bits from a plate with no planning, of course not. People use the phrase "bits from your plate" when working on the assumption that the food is balanced and suitable.
