Quick response to people who comment how small my baby is

[Gabbbbbbby]

I'm getting so fed up of comments about my DS's size... He's 10 months, love his food and is tracking just above his 9th centile weight line, which he's been on since birth. He's always been a little baby and when he was younger I didn't mind people commenting so much, but now he's getting older I'm getting increasingly fed up! He's not even that small! He just doesn't have rolls of fat.
I'm sure I'm projecting, but I just feel people's judgement when they comment that he's small for his age, like having a big baby is somehow better. I'm sure this will continue through toddlerhood, I can't imagine him suddenly becoming big for his age, so any tips on quick, non-snarky comebacks when people comment?

Haha @FluffMagnet, that's exactly what I'm worried about - still feeling I have to defend his size when he's a grown man!!
I think the PPs are right and people just don't realise you take everything anyone says to heart about your baby. But thanks @Kaiserin, for understanding. It's not acceptable to comment on someone's fat teenager, so there is an aspect of it just being a bit rude!

@Eggcellent29 well yes, that would be a nice quick way to shut them down

Honestly it's just people making conversation, they're not being rude.

But all but the most obtrusively thick people must realise that everyone remarks on the size of an unusually small/big/bald/hairy baby, and the parent to whom the remark is being made will find it tiresome.

I'm sure the people who say on a daily basis to my six footer female friend 'What's the weather like up there?'/'Is there snow on top?'/'You're tall, aren't you!'/'I bet you're a gift to a basketball team!' think they're 'just making conversation', but you'd have to be fairly thick not to recognise that (a) you don't actually need to verbalise everything you become aware of and (b) it's the equivalent of the two-hundredth rendition of 'Ten Green Bottles' to the person who is the target of this kind of 'making conversation'.

It's perfectly possible to just say 'What a lovely baby'. You're not tasked with describing his salient points to the universe.

I had 2 of them. Neither grew hair until older either but were physically very able cue lots of comments about how good my "baby" was at running when she was nearly 2! They come in different shapes and sizes, as long as they have good nutrition and aren't too overweight (much more common) all is good

Fully expecting us to go through this... my baby was very premature and also IUGR (so was deprived of nutrients in utero so underdeveloped when born). We always get comments he looks like a tiny newborn even though he's 4 months now. I just can't be bothered so just smile and nod.

I had a teeny tiny little 2nd centile girl. People were always commenting on how little she was and how advanced she seemed (they assumed she was a lot younger than she actually is). We got stared at constantly when she started walking at the very normal age of 13 months because she was so short and slight she looked like a much younger baby. I just nodded and smiled when people commented. Mostly people just want something to say. I now have a perfectly average sized boy and I keep getting told what a chunk he is!
