There are a lot of reasons to savour awake time with your babies! I started awake time with baby bird at 4wks and have more or less done so everyday since!
In the morning when she is first up I use her under-the-sea playmat. This is always the first awake time of the day. Later on I just read to her or play with her in our play-area downstairs as her mood requires.. She also does tummy-time on the mats downstairs in the afternoon. At 8wks old she was able to hold her head up both when on her tummy and on her back, and roll from side-to-side!
We love awake time!
