A one handed mum is still a mum
You need to stop. I know that the Health Visitor only 'meant well' but that doesn't stop the feelings of shame and embarrassment flooding through your body as they check that you can hold your newborn safely. Of course you can and deep down, you know that you are being the best mother that you can be. Unfortunately that doesn't mean that the 'well wishers' and other people who feel the need to ask if you are 'coping' won't drag you down a little and make you doubt yourself every time.
Breathe. Remember, you've had this all your life - people wondering that because you were born without a hand it somehow means that you are not only incapable but also stupid. You're neither. You are capable, stronger then you know and most importantly you have a husband and family that do not doubt anything about you. Remember that.
Holding her, breastfeeding her, changing her nappy, sorting out the car seat, dressing her - you can do all of it. It might take a little practice but you'll get there. Like you always have. As she gets older, she'll instinctively help as well - she's so bright and considerate of everyone around her. She won't see what some of them do - she'll only see her Mummy who plaits her hair everyday before school (nit prevention!), ties her dance shoe laces and cycles alongside her on bike rides. And she'll tell other children that her Mummy can do 'anything.'
So just stop now and forget the Health Visitor visits that you dread each week. They mean nothing - your daughter is testament to that.
Chin up - you really have got this.
ps In the coming years there'll be presenters on the television just like you - even on Strictly!
