You officially have an 18 week old baby!

Your baby is pursuing world domination over you

Your baby is 18 weeks old! These past few months have flown by, haven’t they?

By now, your baby has likely discovered his feet and toes (and might even be putting them in his mouth) and can easily hold his head up and look around during tummy time, undoubtedly plotting which household items he’ll use in his pursuit of total domination over you.

Are you still wondering if it’s time to introduce your baby to solid foods? If he can sit with support and looks as though he might take a chunk out of your hand in an attempt to scarf down that burger of yours, he’s probably ready. Just be sure to keep that burger out of range at first, instead opting for creamy and smooth food options, such as single-grain baby cereal and puréed fruits and veggies. You don’t need any apocalyptic-grade diaper blowouts. The ones you’re already dealing with are bad enough.

As far as brain development goes, baby is also able to match sounds with their appropriate actions at this point, which means if he were to look at two people — one reading a Mother Goose book and one dancing while belting out the lyrics to T-Swift’s “Shake it Off” during a marathon cloth-diaper cleaning session, for example — he would be able to appropriately recognize which of those individuals was reciting a nursery rhyme and which was having a solo dance party, if he were to hear those sounds in isolation. But don’t worry. He won’t be able to tell anybody just how terrible your dance moves are for at least another two years or so.
