DD is a little over four months, and is a long and petite baby. She fits nicely in 0-3 or 3 month tops and dresses, but her legs go on for days. Most of her 3 month pants are borderline capris at this point, and several of her sleepers are being stretched by her length.

I've tried the next size up, and she's absolutely and utterly swimming. 6 month sleepers look like trash bags, and fall off both her shoulders, and the elastic waistbands of 6 month bottoms don't even touch her sides.

I'm looking for a temporary solution until she bulks up a bit. Should I just pin 6 month pants? Throw thick tights under her too-short leggings? I don't want her little legs getting cold as we head into chillier weather.
