When you start to have a few minutes A that aren't taken up with feeding, burping and changing it's nice to just look at one another and have a little chat or a song. You can hang or pin up something visual for LO to gaze at too (like a cot mobile). Bold black and white contrast is good, just print out or draw some parallel lines, geometric shapes or wiggly lines with a broad black marker pen onto white card. My LO loved staring at strong black and white cards and also loved his jungle gym mat that had hanging toys. I think we got that when he was around 4 weeks old.
