According to a poll carried out by nursery brand Munchkin, second children can be left to cry for longer and will go onto solid foods at an earlier age. They are also more likely to be left to manage their own food, and will be picked up less when they are hurt.
A third of the 3,000 mums with two or more children who were polled, said they feel more comfortable leaving their child to entertain themselves while they get on with the housework, whilst 33 per cent only changed a nappy when absolutely necessary rather than after every feed.
The findings also revealed 26 per cent of 'second time mums' are less likely to make the baby their own special meals after weaning, and simply blend whatever the family is having, with the same number admitting they started weaning their next child at four months rather than at six months as with their first-born.
Second children are even encouraged to develop more quickly – as mums expect them to reach important milestones sooner and trust them with a knife and fork earlier.
They will also be allowed sweets and chocolate at a far younger age than their older siblings, and can watch 'older television' at an earlier age, too.
And rather than taking a long maternity leave, working mums of second children will put them in childcare so they can return to work sooner.
The poll also revealed that six in 10 mums thought they were overly attentive with their first child, with 42 per cent admitting they worried more about them than their second child.
Munchkin spokesperson Claire Rayner said: "This poll is very insightful and confirms that having two children means life becomes even more of a juggling act for mums. With the first, there is just one child to look after and mums can give their undivided care and attention. It is understandable that mums will be more confident the more children they have, and therefore less worried about things."
