We've had ds at the table since he was about 2 and 5 months (when we started putting dd in the highchair). We try to have breakfast all together - me dh and ds actually at the table and dd in her highchair pulled up near the table. Occasionally, at the weekend or if dh comes home early, we'll have dinner together as well. But usually ds has to eat earlier as he's pretty much too tired to eat much later than 6.
