My ds is 21 weeks old (was born a week late if that makes any difference!) - I'm keen to do BLW. I haven't felt any pressure to wean before now as he hasn't seemed ready at all, hasn't been feeding more frequently, and has gone from feeding once in the night to twice but it's not too terrible.
In the last couple of weeks though he has become much more co-ordinated at grabbing things and getting them into his mouth, and has started to sit with very little support - he can sit by himself but can only sustain it for about 30 seconds. He's also very interested and vocal when we're eating.
Is it possible to do BLW this early? I'll probably try to leave it for another week or two, but is there anything I should know/do differently as he's younger? I'm tempted to sit him in a bumbo chair with a tray and just put some food in front of him and see how he does, but not sure if this is the best way to go about it.
