yep, I got the same here! my own father fed him chocolate at 3 months!
and to be perfectly honest my
ds was a really good sleeper until we started solids so dont believe all the BS about it making them sleep better, it didnt here!
how about telling them that until 6 months of age babies have an open gut which makes it really easy for them to absorb all the goodies from your bm (antibodies and such) but it also makes them highly susceptible to infection from foreign things (like food before they are ready!)
Bm is the best thing for your baby, and food is only supposed to be fun in the first year anyway, sounds like you are doing a fantastic job.
you are so not alone xx
