Well my HV where I lived said it was perfectly fine for me to wean DD at 4 months, I could have held off if I wanted to, I'm not ashamed to admit, I weaned her more for my benefit and not hers. My DD is absolutely perfect, I again followed the "guidelines" and got rid of the bottles when she was 1, we started using a cup straight away, we also put her straight onto cows milk. She's 3 years old, eats with a knife and fork, eats all her meals at the table with us, the same food as us, would not touch a chicken nugget or a chip to save her life, so I don't think my parenting skills are too bad...she eats all the same meals as we do, and has done from as long as she could, cottage pie/lasagne/curry/pies/rissotos/paella/fish+seafod/steak,etc etc my partner cooks 99% of our meals from fresh too, so no-ones going to make me feel guilt for weaning her early, she's turned out perfectly fine.
I've mentioned more than once, I don't want to wean J, If I can help it...I've been through so much with my health, yes I'm "supposed" to know all these thing's and I can't remember for the life of me how much milk DD was drinking at 5 months old etc, but she was eating now etc. I went to the HV for advice, on whether to carry on with giving him his 1am 7oz feed and 4am 7oz feed. He's having all this milk, he's really chubby baby, and yet he's not gaining, and he's dropped down a percentile, that's all.
BREATHE....My vent is over...
