HI,
With my first i borrowed a chair, its one that lies flat and you can rock it with your foot, ideal for sending them to sleep. Abbey would even sleep in it at night sometimes and its ideal if they get a cold as they need to be slightly elevated, you cant really do that with a moses basket as the matress is so thin. This chair can be put in any reclining position and has a saftey catch to stop it falling forward for when they are more active. I then got given a normal winnie the pooh bouncing chair when abbey was 3 months, which i would put toys around them on cushions, it encouraged them to reach for it and they didnt have it hanging in there face 24/7. I do think the rocking aquarium mentioned above is good i used a friends when visiting and my boy went straight to sleep.
