hi muffin
my twin daughter had a bad case of colic when she was around a month old. you need to check whether your baby has this since crying a lot in the evening usually means this. if u are not breast-feeding it will be worthwhile to invest in anti-colic teats for the bottles. play some music to soothe and put baby to sleep on tummy. also try to finish your chores early so that your evening is free and try to have a nap when baby sleeps. you won't feel too tired then.

good luck
