After reading what you have all gone through with your babies with their needles, I think I'll be asking my doctor if we can split them as really its up to me to decide, the doctor can really only advise what is best and I just think 4 needles at once is alot, I'd rather him have 2 and then go back in a month and have the other 2. So I'll let you all know how I get on after my visit to the doctors tomorrow. I am also having my 4 1/2 year old vaccinated at the same time for her 4 - 5 yr old needles she is due 2! So I think its going to be a fun day for me, I'll have the panadol all prepared before we make the trip to the doctors for them both! So far both my children haven't had any reactions to any of the vaccinations, only the first time my daughter had her 2 mth needles her leg swelled a bit where the injection went in, which is apparently normal but she was in alot of pain with it and kept screaming and was upset for a few days afterwards, so after that the next lot of needles I had the needles put into her bottom, the doctor wasn't happy about doing it there, but again thats my decision so that is where the doctor put the needle in and then I had no further problems.
Thank you all for all your advice, been a great help.
