What are your activities with the baby while they are awake?
Emily has a few hours of "quiet alert" time during the day now so either me or DH try to talk to her and just get some "face time" in with her. In the afternoons when Nicholas is awake and playing I will put her in the bouncy chair and she looks at the animals hanging down (I think). Tonight I put her in the swing and turn on animal sounds while I got some stuff together for dinner too. At night after Nicholas is in bed we snuggle and talk to her while we watch our shows on tv. We might break out the playmat and start some tummy time soon.
