I was at toddler group yestaday talking to a young mum, her dd is 15 weeks, on 3 meals a day, she weaned her at 13 weeks and gave her baby rice at 8 weeks (with her milk) 
She said i should wean dd2 (12 weeks) 
And she works in child care (she should know better)
My dd2 is very hungry but she's fine with her milk at the moment, i know i will have to wean her a bit early but as close to 6 months as possible. 13 weeks is just mad
