We were living abroad and moved back when baby was 6 months. He has had vitamin d drops since birth. He eats a varied diet and loves eating plus he still breastfeeds 2-3 times a day. He's just turned 1 and a friend with a 6 month old asked me what brand vitamins I give him and when I said just vitamin d she said that I should've been giving him others since 6 months. Ive seen one health visitor since moving back at around 6 months and she didn't mention anything about vitamins. Now I'm worried that he's missed out. I went swimming the other day and noticed he was quite small in comparison to another one year old (most of my friends have different aged babies si it's hard to compare) and now I'm worried that the lack of vitamins have affected him. He's a very happy, healthy looking baby and I wouldn't have been too worried if my friend hadn't said anything but now I'm feeling like a terrible mother! Will it have affected him badly?? What vitamins should I get be him/any particular brand?
