We just started the tucker sling/wedge at 4 mos and the past two nights he slept 6 hrs and only woke up twice. Before that it was three hours and then every hour after that. He won’t nap in it though, so I just put pillows under his mattress for a little incline during the day. He’s a tummy sleeper though, so I don’t know how well back sleepers like it.
Maybe you can find a sling on ebay and just try pillows under the mattress to get an incline that she’ll approve of? I found a new sling and wedge on ebay for a lot less than full price. At least you can sell it when you’re done and get some money back.
