We have DS (4yo) and DD (2yo) and had always wanted a third, but having found DC2 pretty tough going (silent reflux, "assertive" as a toddler, etc) we are going round in circles trying to decide whether we should stop at 2 or go for a third. One factor is DH's age - he would be 47 when DC3 came along if we TTC now. Do you think 47 is "old" in this context? DH raised this as a possible con. Would you perceive the risk of complications to be greatly increased with paternal age? I only ask because my bro has ASD and I'd read that paternal age can be a factor in ASD. Sorry about the series of questions - in total decision-making quandry
