(reading time ~9 1/2 minutes) 

This article will delve into 1-3 month milestones for babies. You may also wish to check out 4-6 month milestones, 7-9 month milestones, and 10-12 month milestones. 

Milestones are meant to be general guidelines. They are variable and flexible. No two individuals, and so no two babies are the same. Some will hit milestones a little earlier and some a little later. Very likely, your baby may be hitting certain milestones a little earlier than usual and some a little later. 

When To Speak With Your Pediatrician 

However, milestones give a general indication of what to expect and an idea if there's a problem you want to speak with your pediatrician about. My philosophy is "when in doubt, talk it out." It is better to come to your pediatrician earlier with concerns in case there are issues you can be working on.

For instance, many physical and cognitive milestones are linked to having enough tummy time. If you are having milestone challenges related to this, it's certainly something you can take action on.

Another example is talking a great deal with your child and repeating the sounds he makes, which are essential factors that promote more give-and-take "conversation" if you're concerned with development in this area.

The important thing is if you have any concerns, bring them to the attention of your pediatrician early on. I'll be listing some instances when you should be doing that anyway.

Says pediatric occupational therapist Rachel Coley, "I encourage parents to discuss all developmental concerns with their pediatrician, but generally I lean toward the proactive approach of early intervention if there is an area of development with multiple lagging milestones – or there isn't progress toward a major milestone by the end of the expected age range."

I will note when there is a range of months; you might expect a developmental milestone to occur. Also, understand that milestones are ranges and not averages.

For instance, in most cases, a baby will start walking between the ages of 9 to 18 months, but on average most babies start walking between 13-15 months. So, it may not be helpful to worry if your child isn't walking by nine months, while there are still three months remaining for her to be an earlier-than-average walker.

And an important note for parents who have had premature babies. Preemies usually reach their milestones according to their due date rather than birth date.

So, for instance, if your baby was born ten weeks early, its development will generally match that of a baby born ten weeks later. Incidentally, most premature babies will "catch up" to babies born full-term by the time the preemies are two years old.

And so here in user-friendly bullet points are the major developmental milestones 1-3 months. We'll go through each month, one at a time.

About the author 

Dan Sperling

I'm the proud father of two great children. They are grown up now, and although I would have preferred to be a stay-at-home dad, I had to work. Luckily, I could work out of my home so I was around a lot. I ran a video production company, had a couple of great guys working with me and it allowed me to be around the children a lot. I was the "fun guy" for my kids and fathering was something I just took to.
When my daughter became pregnant, I was glad to see my son-in-law was doing everything right--or as good as it gets--we're always winging it, right? It got me thinking that so many dads would like to be more emotionally involved and knowledgeable when it comes to their wives' pregnancy and the first year of their children's lives.
