We bring our baby here when he was 17 months, but he got sick frequently after he was sent to day care, and transferred to another day care after we moved to another city. He got high fever last week and had to stay at home for the whole week. We had to take leave alternatively. There're 9 got sick among 15 toddlers in the day care last week.
If there're really someone could look after your baby for several months, and your baby is young, it's better to send him/her back, but not for a long time. However, we don't regret to bring him here.
