Infant Development: 2nd Month Milestones

You may not notice too many changes over the next month from your baby’s first few weeks. These are a few infant development skills you may notice in your baby during their second month.

  • Lifts head to 45-degrees while on stomachDSCN2642
  • Focus and follow an object in an arc within 6 inches above the face
  • Bobs head forward while in a sitting position
  • The strong grasp reflex decreases
  • Responds and may vocalize to familiar voices

Keep in mind that babies will develop at their own rate and may do some or all of the above listed developmental skills. If you notice your baby hasn’t achieved any of these skills, check with your doctor. It may be perfectly normal, though in some cases a delay in development could be an indication of  a medical problem.

Your Baby May Also

  • Raise chest while on stomach supported by their arms
  • Roll over one way (tummy to back)
  • Focus on a small object
  • Bring both hands together
  • Lift head to 90 degrees while on stomach
  • squeal in delight

2nd Month Well-Baby Exam

Along with the physical exam as well as questions regarding baby’s eating, sleeping, and overall general habits, these are what your pediatrician will be looking for in infant development at your baby’s second month check-up:

  • Baby’s measurements: weight, length, and head circumference
  • Routine vital check: same as previous assessment during the first month visit
  • Developmental milestones: evaluate head control, vision and hearing, observing response and interaction
  • Address and recheck any problems from your prior visit or concerns

If you opted to have your child vaccinated (as discussed at your baby’s first month visit) they will receive their first full round of immunizations at their second month check-up. Some immunizations will be given in a series of multiple shots over time, such as the Hepatitis B vaccine. Your doctor may put off certain vaccines if your child is ill or has certain medical conditions. Generally, most babies will receive these vaccines:

Hep-B (if not given in the hospital) The Hepatitis B vaccine is given in a series of 3 shots, the first generally at birth, the second between 2-4 months, and the third between 6-18 months.

DTaPDiptheria, Tetanus, Pertussis (aka whooping cough) vaccine. This vaccine is recommended to be given at 2 months, 4 months, and 6 months, then again between 15-18 months.

Polio – this vaccine has virtually eliminated the Polio disease. There are two forms of this vaccine, an active form that is given orally and an inactive form given through injection. The American Academy of Pediatrics recommends giving the inactive injection to infants at 2 months and 4 months. They will receive a third dose between 6-18 months and the last dose between 4-6 years.

Hib – Haemophilus B vaccine protects against the deadly infection which often leads to meningitis, epiglottitis, septicemia, cellulitis, osteomyelitis, and pericarditis that can occur during infancy and early childhood. It is recommended in a series of 4 shots given at 2 months, 4 months, 6 months then again between 12- 15 months.

PCV – this vaccine protects against the pneumococcal disease which can lead to meningitis, pneumonia, and ear infections. It is recommended in a series of 4 shots given at 2 months, 4 months, 6 months and again between 12 and 15 months.

Rotavirus– this vaccine helps reduce the number of babies infected by the Rotavirus infection which causes severe diarrhea (8-12 times in a 24hr period) and low-grade fever, usually leading to admittance in the hospital. It is given in a series of 3 shots recommended at 2 months, 4 months, and again at 6 months.

Your doctor or the nurse should give you forms with information about the shots as well as reactions to look for. Discuss the potential for reactions and how to treat them.
