DD aged 15 mths took her first steps out of the blue on Thursday. She had only been walking holding hands for the first time a day before that so came out of the blue! She did several sets of between 3 and 5 steps that day. Since then she hasn't walked on her own apart from the odd side step when standing alone. Is this normal? Was hoping she'd be walking properly ina few weeks or so- not so sure now!
