Is it wrong that a health visitor suggested I give my 21 week old BF son some baby rice to help him sleep through the night? I have got used to waking 2/3 times at night to feed him & don't mind. THe HV told me 'they should sleep through the night at 6 months' which I think is just a rubbish generalisation - especially with breastfed isn't it?? He isn't demanding more than normal but my husband now thinks DS needs more nutrition - he was under his 'centile line' at his last weigh-in. I know that the chart he is compared to is for formula babies but he was small to start with (6.6 - now 13 pound 1) and so we are now paranoid!! Any opinions?? Thanks
