I saw my maternal health nurse today for my little boy's 12 month assessment. She said that at this age they should not have more than 600mls of dairy each day. This includes all dairy (milk, cheese, yoghurt, etc). Luke is currently having 600mls of milk each day, plus a tub of yoghurt and lots of cheese, so I need to cut back. Since he went on to cow's milk, his poo has been really sloppy, so she said this is because he's having too much milk.
She also said that bottles should be completely cut out by 12 months and they should drink all their milk (and water) from a cup. I'm not too sure of the reasons for this.
I was originally planning on getting rid of his bottles at 12 months (mainly because his sister had milk in a bottle before bed until she was three and it was really difficult to stop it)
However I've decided that it's not really a big deal if he keeps having bottles. He's still a baby and he really enjoys relaxing with his bottle. Maybe when he's 18 months, I'll reconsider.
