Hey Roofless, my DD is only 10 weeks so doesn't know she exists let alone another kiddy just wanted to let you know that I went to my first mothers group today and there was a daddy, I made sure I went and had a big chat with him, so we're not all like that.. The nurse also mentioned that new groups start every 3 months and we're more than welcome to join the next one if this doesn't work out for whatever reason, or if we'd just like to make more friends in a new area. So I'd say contact the local nurse or playgroup australia and give it another go!!
I really think there should be a dads group not just for SAHD's but for all dad's - they need to talk too!
