We have just started BLW this week. DS is 5-1/2 months.
How do I know when he has had enough? At the moment, I'm just letting him go until he starts to whinge in the high chair but I'm not sure if we should stop earlier. Some nights he's ok for 30 minutes, other times it's only 10 minutes.
On a side note, I am so glad that I've gone down this path (at least in my extremely limited experience). I hate the thought of having to prepare separate meals and purée everything. It's great fun to see everything mashed everywhere and DS' reaction to it all.
