I'm looking for a co-sleeper bassinet. My son is 5 weeks old and 23in long. The bassinets I'm finding are all around 28in. The longest one I've found is 32in but it's pretty pricey at $70. Anyone have any suggestions?

This is the one I found and like but really wouldn't like to spend too much. It's the Serta iComfort
