My son had his 4 month needles on Monday, and he was pretty much normal for 3 days after, but from day 4 he has started to grizzle a lot more, and won't sleep for long at all during the day. Normally, he puts himself to sleep, but I am now sometimes having to rock him sleep.

I am fine with all this if I knew if was just another 'stage' or growth spurt, but I am wondering if anyone elses bubs' had a delayed reaction like my sons due to the needles?

Any feedback would be greatly appreciated.
