I've decided to give this a go as normally DS eats, sleeps then plays. Today I've done it the other way and he's had a good nap both feeds. He's actually fallen asleep of his own accord on the living room rug where I put him while I took something into the kitchen. Could hear him giggling one second then he went quiet - stuck my head round the door and he's gone off. How long for I don't know but I feel much happier today - can't believe I didn't think tiring him out first would work lol. Will try and stick to this routine as much as possible - at least when we're at home.
Now time to read the trashy magazine my OH bought me when he came home to me crying yesterday as I couldn't settle DS. He'll see a different woman today!
