Immunisations and sleepiness

[Learnermamma]

Hi,

I have heard that it's perfectly normal for babies to sleep a lot after immunisations, but a week later?
My 10 week old daughter hd her first last tuesday and everything was ok, but the last 2 days she has been sleeping a lot more during the day - and sleeping through last night! She has also developed a heavy cold since the weekend so am wondering if this tiredness is something to do with fighting this off or the immunisations - or both!!?

Mine have never had any reactions that last more than a day or so after an injection. Sounds like her sleepiness could be due to the cold but if you're concerned get a Dr's appointment tomorrow.
