DH in particular is still worried.
DS is 8 months. He's been crawling for months and furniture cruising for 2 months, stands unaided (tires to step but falls on bottom), says "mama" and "dada", etc etc
But he's so small. He's on one of the lowest centiles there is, but was 7lb 8 when born.
I have 0 concerns as his Mum and neither does any of the health professionals I've seen. But I don't know how to put DH's mind at ease.
He's 6'3 himself, and was a chunky baby. As were all the babies on his side really. My nephew of a similar age is on the 98th centile. His brother is on the 99th.
Our DS is still in 0-3 clothes and looks quite comical standing proud as punch 
But still, DH isn't happy, I can tell he still isn't.
He works in London all week so no chance of him chatty to a health visitor or something to ease his concerns.
But the pressure of me needing to 'bulk him up' seems to always be lingering.
He is still on the breast a lot but this doesn't replace meals.
His cousins are also breast fed and they're bulldozers so I don't think it's related.
