Do you mean night, day or both?

DD was a September baby but she was tiny and still in teeny clothes during the hot months At night she just wore short sleeved onesies and a 1.0 tog or 0.5 sleeping bag (depending on how hot it was). The warm days we had when she was still being swaddled, she was often just in a singlet and nappy and wrapped in a muslin.

As for 'real clothes', I bought lots of short sleeved and singlet sleeved onesies from both Target and Myer (Sprout, at Myer, have such a gorgeous range but I will confess to being a complete Sprout addict!). So DD was still comfy and the outfits were practical but she didn't look like she was wearing pjs or underwear all the time, ITMS.

PS: I'm in Perth hence why we had warm weather early and frequently despite DD being born early Sept.
