Should I be worried? She's 15 months and crawls very well (although was very slow to do so) and she can pull herself up to standing. She'll also walk holding onto both my hands - not far, a few steps and reluctantly. Sometimes she'll just refuse. Should I be worried that she's nowhere near walking yet, or even cruising? My son was slow to walk at 16 months, but he was cruising holding onto furniture by a year old. Could it be something underlying or normal? Any advice or tips to help her would be appreciated! Tia
