Chloe is 14 months but still really tiny and gets sick quite quickly - almost all the time - on and off. Any way I sterilised her bottles till she was 12 1/2 months and now I still do them if she is sick - my question is should I still be sterilising them anyway? She has 1-2 years formula and I know when my other 2 were tiny it was upto 12 months but should I still be doing it as she is still on formula? And what about her juice/water beakers???
