How many months can a baby be held upright?

Patient's question:

No

Doctor's answer:

Babies can usually be held upright after three months, but be careful not to let the baby bear too much force. Children generally get their first milk teeth between 6 and 8 months, and now at five and a half months, the baby has already sprouted milk teeth, which can basically be determined not to be calcium deficient. Using a bottle is essentially unrelated to breastfeeding. What you mentioned about the baby not being able to suck the bottle may be due to the baby not being hungry or lacking the desire to eat.
