I was told to spoon feed my 2 boys early (I also have 2 girls who slept well) to try to make them sleep better. My older son is now 7 years old, and I gave him baby rice made with my breast milk, and it made no difference at all to the way he slept. He still takes less sleep than anyone else in the house. I spoonfed him at 12 weeks old.
My youngest son is now 13 months old, and I didn't spoon feed him until he was almost 5 months, as i knew it would make no difference. He didn't stop feeding through the night until he was about 11 months (stopped b/feeding at 10 months).
My 7 year old has eczema, and I blame myself for spoonfeeding him too early.
