Is it true baby younger than 3 months cannot bring the baby out? I was scolded by my mom for bring LO out to shopping mall. Because after I return home my LO keep crying and it become everyday thing. And she assume that is because I bring her out.

Nonsense! It's crazy - who is going to stay at home 24/7 with the baby? U? If u are the mummy, everyday just see the 4 walls and baby, u will go crazy - depression I mean. Some pple say baby will easy to sick but the thing is baby will be kept close to u, don't let baby anyhow touch things(catch germs), u also practice reasonable good hygiene when outside (who knows who touch the lift buttons huh?) It most definitely is not because of that one trip tho it might have "scare" the baby because the environment is too stimulating. Just calm baby down will do. Try to have a proper routine for baby and stick to it as much as possible otherwise baby will inevitably tend to be cranky when out of routine and not enough sleep
