My first child, also don't know many other toddlers to compare but my 16 month old counts to 4 and says around 30 different words I'm just wondering if this is normal? She was quite behind with milestones other than walking at 10 months just kind of shocked with things she says and does sometimes can also string 2 words together for certain phrases like "all done" is there anything I should be doing to encourage her to learn more?
