Oh Hun you must be worrying. My lo is also sleepy after shots. It could be the rotavirus one that's upset her. I'm going to tell you what my leaflet says
" many millions of doses of the vaccine have been used and it has a good safety record. Babies who have had the vaccine can sometimes become restless an tetchy. Some may develop mild diorreah.
In very rare cases (about two in every hundred thousand babies vaccinated) the vaccine can affect the babies lower gut and they may develop abdominal pain, vomiting and can sometimes pass what looks like redcurrant jelly in their nappies. If this happens you should contact your dr immediately."
Please don't think I am in any way trying to scare you. I'm pretty sure when my lo had the drops it was only the redcurrant jelly in the nappy bit you really need to be concerned about.
Go with your gut Hun. Nobody knows your baby better than you do. If need be can you get her checked out by another dr just for piece of mind? I'm sure she just feels quite unwell and will be back to normal soon
