I do go to mothers group. But, they are all in their very late 20s to late 30s. My sister is the only other young mum I know, she was 20 when she gave birth to her first (born sleeping at 20 weeks) and then 21 when my niece was born. But she is moving to New Zealand this week.
Its a tiny country town.

Getting to mothers group is hard, as DD usually goes to bed for her nap at 9.30am and MG starts at 10am.
lol, the only week she was up and ready to go - it wasn't on!!! :-)
