Although my 5 month old DD is thriving on a diet of breast milk only, just about all my family and friends with older children think I'm mad not to have started weaning her already. The main reason for their 'concern' is that she's not sleeping from 7pm until 7am (I think 11.30pm until 6.30am most nights is pretty good!) They think that weaning her now will fill her up more and get her to sleep through the night. I understand that there is evidence of a link between weaning before 6 months and allergies. As my DH suffers from asthma and an allergy to cats and feathers, and I have eczema, we are keen to avoid our DD suffering from allergies too so if weaning at 6 months is a way to do this, then I'd like to give it a go. So my question is this - does anyone actually know what research was carried out to prove the link between early weaning and allergies? It would be really good to have your views before my mother arrives for the weekend
