I am completely amazed by DS, now 5 mos. He's always been a very chatty baby and has recently started to make the most peculiar noise. The nearest I can get to it is that it sounds like a flautist who can't decide whether to play a trill or have a gargle! To me it sounds like it must be a very difficult noise to produce but I am clearly wrong as he trills and/or gargles away day and night in the cheeriest manner. It's very endearing. What are the weirdest sounds your LOs have made?
