I've been lent a lot of newborn and 0-3 clothes for my LO due in about a month, which is great. (Unfortunately my MiL is going to give me a lot of hassle about putting our (probable) girl in "boy's clothes" - like it matters! - and will probably rush out to buy pink and frilly stuff that I will have to hope gets badly puked or pooed on. :() Anyway, I'd like to buy some clothes myself, preferably unisex just in case they were wrong at the scan, and I really like Next's Animal Brights range. But I'm confused about the sizing; instead of newborn and then 0-3 months, etc., they have first size, up to 1 month, up to 3 months, and I don't know what's best to buy. I had a scan this week and they reckoned LO will be about 8 lb, maybe a bit less, for what it's worth.
