Don't be so sensitive, bruffin. I have just searched on your name to find our previous thread and there are 6 threads in the past 3 weeks where you pop up telling people their evidence is out of date, that now the guidance is that waiting to 6 mths is a cause of increased allergy, and that 4 mths is fine because of this...and we simply don't have the evidence for these assertions.
You misrepresent the EAT study. It is looking at the apparent rise in allergies since the 1970s (not since the UK guidance change in 2003 - that would be far too recent for any change to show up, especially as very few people wait to 6 mths any way) and speculating that delayed introduction of known allergenic foods does not reduce allergy.
Fair enough to investigate this, but not for you to use an ongoing study to tell mothers it's ok to introduce solids at 4 mths - especially not in a thread where an OP is asking for support against her mother who has been pushing her to give solids from 6 weeks.
I agree with you that the whole issue has very little to do with allergy - somehow or other, talkboards like mumsnet are awash with people who believe that solids before 6 mths increases the risk of allergy. We have no good evidence to show this. People don't need to worry that solids before 6 mths (but after 4 mths) are likely to damage their babies either, and I think people worry unnecessarily about this.
It's to do with nutritional needs - babies usually do not need solids before about 6 mths. After about 6 mths, they usually do. We have excellent empirical evidence for this. Giving solids before a child actually needs them risks the solids taking the place of the milk - again, we have good evidence for this. When solids take the place of milk too young, the risk is nutritional deficit...but as a direct link to damage, no, and I think it is helpful when people chill about this and watch their babies for genuine signs of readiness, rather than watching the calendar.
Genuine signs of readiness really don't happen before about 4 mths and almost always happen by about 6 mths. If people need actual time guides, then offering solids at about 6 mths is fine, and if they are convinced their baby is showing signs before this age, then to offer sooner than this, but not to shovel it in
A baby given something suitable to hold and lick will probably not manage to eat more than he actually needs or wants or can cope with digestively, so the OP's baby prob could manage a lick of a bit of banana that her grandmother is so anxious to give her, but she doesn't need it nutritionally or developmentally.
I don't know why you say I denied other countries have different guidance. I didn't. However, worldwide, and European, guidance is mostly for excl bf to 6 mths - there are some exceptions, which I am aware of.
