My HV was telling me 6months and I thought it was a load of crap. What she was telling me contradicted what she was also telling me about milk and ignoring the needs of our baby.
DD - PFB - was born at 5lb, was BF and by 4.5 months was 'technically' underweight, allegedly (turns out probably not, was not a BF chart), and the HV mentioned possible failing to thrive.
DD would not take a bottle for top-ups. No advice other than keep trying, she will scream but she wont starve herself. HV stated it was probably a problem with my milk.
We asked if we should wean her early. OH NO, cant do that, guidelines say 6 months! So, we cant give her a bottle, we cant feed her enough of my milk, and we cant wean her. So she will starve .
So, we ignored her, went to GP who said nothing wrong with her weight, she is a small child, will always be small, however if we were concerned, wean her now.
We waited until 5months, but had become so stressed about the HV stating that it was my milk, that we said, to hell with her advice about weaning, she needs the food.
And it turns out, nothing at all wrong with my milk. When weaned, she ate a ton, and still stayed small, on the same plot as always on the chart.
I think what I am saying is that 1. 6 months is not always right. 2. HV should not just spout governmental guidelines without the knowledge to back it up. I felt so lacking in confidence in anything she said, we totally disregarded it.
Only went back for her 8 month checkup.
