Somewhere between 3.5 months and 4 months of age, your baby will likely go through what people call a regression. I don't love that word because it's implying that your baby is taking a few steps back, when in fact, they are taking giant leaps forward.
That being said, it sure seems like things are not going so great. What I have noticed is a WHOLE LOT of crying! A LOT LESS sleeping, and SO MANY smiles (thank the lord! It makes the other stuff a little teensy bit more bearable!)
What you should notice about babies language:
Generalized mouthing is a period of time (birth-4/5 months). During this period, babies suck on anything within arms (or mouth) reach. By 4 months, baby is gaining control over sucking, decreasing rooting, and decreasing gagging.
The toys you see that have more of a point to them can be used starting around months 5-6. I'll discuss this more next month!
1. They recognize key people in their lives
1. They start to understand cause and effect
Some people will start solid fooding at 4 months, usually some kind of rice cereal. Personally, I really considered starting at four months, but I had to look at the pros and cons of starting what most consider to be 'early'.
So based on my list, I decided that we have a good thing going with breastfeeding and there's no need to rush food. The kid has his whole life to eat! This list may look differently for your family, so I would encourage you to make your own pro and con list to determine what works best for your family.
What developments are seeing around 4 months?
Did you decide to start solids?
