Depends if you're a working mum. maternity leaves up then got no choice but to put bb into infant/child care. Otherwise is best to look after the little one yourself.
Kids in childcare do fall sick easily cos viruses pass from one to another and goes around. My friend got 2 girls. Elder girl (3 yrs) in childcare for abt 2 yrs and still tend to fall sick and the worst thing was the sister (1 yr) keep getting the viruses and fall sick too. Even though is the normal cough and running nose, too much phelgm being produce and always have to be on medicine. She was admitted twice in hospital already (1st time when she was abt 5 mths).
Fulltime mum will benefit the bonding with child and see the tiny little things like saying the first word, taking the first step.
Enjoy motherhood while you can, nothing beats the smile, hugs and kisses from the little ones.
