My DS has been taking milk only during daytime hours since week 9 - and recently he has been guzzling so much I think that he's going to explode with so much fluid.
So going on the advice of my mother, I tried a little mashed banana after his morning bottle and he absolutely shrieked with joy. After a few days of this, he is now opening his mouth to accept the spoon and swiping at the spoon with his fist (he's not getting it yet though).
No adverse effects poop wise, sleep wise, mood wise etc. Sleeping well through the nights, napping normally and not guzzling huge quantities of milk before bed.
Anyone else on a similar route?
