The singer, 42, gave birth to twins Nelson and Eddy in October and she spoke to France's GALA magazine about how much she appreciates her mother Therese and sister Linda helping out.
She said: 'I didn't have these children to not take care of them, to give myself to them 200 to 300 per cent. I am changing diapers and breastfeeding and that's something where no one can take my place.
'It's tiring but an intense joy. I take things day by day. That's the secret to me. In any case, breastfeeding is more difficult if you are stressed.'
She added: 'Sometimes I find myself in comical situations I don't know how to get myself out of. For example, when both are feeding and one has gas while the other is burping, I don't know which position to adopt!'
