Today my 18 month old daughter fell while bathing , got hit on back of the head . She cried a lot for 10 minutes but then got Normal. She vomited milk too while crying. She was fine whole day afterwards , ate well , slept well. Should I invest in a good quality bathtub ? Earlier I used the newborn tub but after 8 months or so it was not of any help. Also, do toddlers fell a lot specially in bathrooms ?
