Misinformation abounds, sadly.
dd2 is a tiny tot. She was born weighing 7lb 13 oz (not so bad) but by 17 months, still only weighed 16lb. She just didn't grow.
We were under the care of paeds/dieticians since she turned 9 months or so (I think, can't really get too worked up about it) because she was, technically, FTT.
She was also, happy, healthy, hitting milestones, and eating like a horse (after 26 weeks, natch )
BUT, the dietician still advised me to give up bf (from the very 1st appt) as she "didn't need it". And the same woman was very when she ooked at dd2's centile charts, that I'd held off to 26 weeks to wean, as obviously I'd been starving the poor mite (never mind that, post weaning, she carried on sinking off the bottom of the charts - a picture that was plain to see even at that point)
I have to go back to see her again next month, no doubt more pearls of wisdom will be coming my way.
Am off to see the paed later this week, and hopefully we'll get signed off, as dd2 has started to gain weight (I think she may even have crept back onto the charts )
