Knowing when to start weaning your baby can be very confusing for parents, especially with your first baby. Although there is a lot of conflicting information around the subject, new research shows that delaying starting to wean until your baby is six months is a little too late. I believe this is very true and you need to give your baby at least two weeks to get used to solids. This will ensure that from six months your baby can move quickly, ready for the different stages of weaning.
