sunny - have you put this message on the "breastfeeding" section ? I think you will get some interesting tips there.
How much did your baby weigh when she was born ?
According to bf experts (see www.kellymom.com) The proper average weight for a breastfed baby at 12 months is:
2.5 x the birth weight
So e.g. if she weighed 3 kilos at birth, by 12 months she should weigh 7.5 kilos.
My son is now 18 months old (I still breastfeed him) and only weighs 9.8 kilos. He weighed 3.09 at birth, so he is on target for a breastfed baby. I have not bothered with the NHS charts, because they are out of date and NOT based on bf babies who were exclusively bf for at least 6 months.
Please bear in mind that the "average" weight and "average" height given out by most hospitals (including in Italy I suspect) are based on "averages" of a mixture of bf and formula fed babies. Averages for babies bf for 12 months and longer tend to be much lower, because breastfed tend to be leaner (which is a good thing).
If you are interested in getting some excellent advice on a gentle way to wean your baby off the breast, contact your local La Leche League in Italy. LLL is a wordlwide org. If you have trouble finding contact details in Italy, please let me know and I will put you in touch with someone. I am an active member of LLL here in London.
Good luck !
ps - I envy you for living in Italy. It is my favourite place in Europe (shoes, handbags, clothes, food, weather, history, everything is perfect there !!) so I have started to learn Italian on the net !
