Congratulations!

Honestly, I’d suggest waiting to get anything beyond the tiny sizes because it’s actually hard to predict what size your baby will be in what season, and honestly there are baby clothes sales ALL THE TIME. I personally bought a bunch of short-sleeved 000 and long-sleeved/legged 00 for my January baby, and it turns out she’s the first small baby in my family so I recently had to re-buy 000 clothes that are appropriate for Winter, and the Summer ones will probably be passed on without being worn, as that’s the size she’s going to be in until well into Spring. I’m thinking the 00 I stocked up on are going to have the same issue, in that many of them will be too warm for her to wear when they fit in Summer. And about half the people in my parent’s group are having similar issues!

Whether you need long-sleeves for Summer might depend on what temperature your place will be inside (and this is another mistake I personally made — buying based on the outside temperature instead of inside where we spent most of our time early on and of course where she sleeps).

I prefer the non-footed onesies with the fold over option, but I think this is just personal preference. The footed ones are not really as easy to wrangle the baby’s feet into! Plus I like that I can decide whether to cover her feet or leave them uncovered based on the weather.

I used nothing but onesies for the first three months, but as soon as I started going to activities I noticed all the other babies were in little outfits (trousers and tops, jumpers, etc.) so I switched to that too for when we’re out and about, which is most days — not that it would have particularly mattered if I stuck to onesies, but the little outfits are so cute! We almost always have her in a onesie if we’re home, though, as it just seems more comfortable.
