My friend's children who are 4 and 6 drink squash from baby bottles (during the day at home - not at school - and take bottles of squash to bed with them), wear nappies in the car (not at night) and use a Phil and Ted pushchair if we go anywhere. My son was in pullups at night until 8 so I know the battle of accidents when they sleep - it's just seeing them get ready for driving home by lying on the floor to have nappies put on felt strange. Both children have speech problems (6 year old is seeing speech and language specialist) and neither have been to a dentist. I tried to encourage them to walk today but after a few steps they were both too tired and climbed back in the buggy. The nappies and buggy do not affect their health so much as the bottles - I wonder if she'll say to me in the future 'why didn't you say I shouldn't use bottles so long?' Or should I just mind my own business?
