Hmmm haven't tried it yet, but have been having more tea than I used to when I was pregnant (ie. about 4 each day instead of 2). For now she is sleeping soooooo well I don't want to upset the applecart. Might just resort to a hot choccy if I feel the urge. But thanks for all the tips, and if I crack and have a latte I'll report back the results.
