By 12 months your baby may

• sit for an indefinite time without support 
• crawl on hands and knees 
• walk while holding on to the furniture 
• wave bye-bye 
• understand several words, respond to simple commands 
• may point at something they wants 
• say mama, dada, repeat simple sounds 
• respond to their name 
• point to their nose, tummy or the dog, when asked to 

You can encourage development by 

• lots of interaction - point out animals, colours, shapes 
• giving him shape sorter toys, push along toys, building blocks, pegboards with large, coloured pegs 
• talking to them - they’ll try and join in conversation 
• praising them - they’ll love to show off new skills (like waving)
