Breastfeeding would be highly recommended but I must say, it is difficult to start your baby on it initially. Breastfeeding will provide your baby antibodies which will greatly aid his immune system. Breastmilk is also more digestable than formula.
Breastfeeding is troublesome at times as you must watch what you eat, some foods will pass on to your baby through your milk, like alcohol, so you must avoid them.
I'm sure there's more advantages of breastfeeding which more mummies would like to add.
