I have a constantly over-tired 5 month old DD. She sleeps fine at night (once I eventually get her off) only wakes for 1 feed then straight back to sleep till 6/7am.
The problems are at nap time, and getting her off to sleep on evening - she has refused all attempts at a routine and genuinely seems tired at different times each day, but I try to stick to a rough schedule of 3 naps a day and a 6pm bed-time, and I watch her like a hawk for signs of tiredness. What we usually get is an hour or two of screaming and fighting followed by a 20 minute nap.
She is very tired and pink eyed and grumpy most of the day. In the middle of her crying fits she won't let me console her, or hold her, or is interested in an extra feed. She takes no interest in her dummy or cuddly toy. I often just have to put her down on her own while she thrashes around and let her cry it out because she is so worked up she doesn't want anything from me. Eventually she wears herself out and will drop off but I feel she's too little to cry on her own like that, although I can't sit there helpless next to the crib while she screams for ages! Other than taking her out on the buggy 4 times a day I'm a little bit at a loss.
Anyone else seen this sort of tantrum on a little baby?! Is it a phase? its been going on for a couple months now and I don't think she's teething yet.
