If you've moved on from the Merlin sleep suit, how long was your LO in it? DS spits up and drools A TON and twice so far has wet through the sleep suit (I think/hope moving up a diaper size is fixing that). He's only been sleeping in it for maybe 3 or 4 days and I'm already washing it constantly. Buuuuuut... It's expensive so I think it only makes sense to get a second one if he's going to be in it for a while.
Ditto PP. We started using it at about 3.5 months and stopped when he outgrew the 3-6 month size at about 7 months. If you're thinking about getting a second one have you looked on Ebay? That's where we got ours and it was definitely cheaper.
