My helper came when baby was 3mo too.. First night sleeping with baby already with no problem. Hire someone with experience in handling nb..
Hey, One of my friend's hired a helper when her baby was 2 months old and the baby adapted really fast so it should be fine :)
My helper came when baby was 3mo. No transition issues at all! She could carry and put him to sleep from day one
3 mths shouldn't be no problem as long as ur helper knows how to take care.
Hired 2nd m. Takes time don’t worry. They will adapt faster.
