Apologies in advance, this will probably be long but I just want to be thorough in the hopes someone has some advice. Also sorry if it's in the wrong section, it's a bit of everything so didn't know where to put it.
My DD is one week shy of 8 months. At 7 months she was on a good schedule of 4 x 180ml formula feeds a day (Karicare HA, no judgement please), three solid feeds a day - a combination of purees and finger foods, and two or three regular naps a day. We have a regular bed time routine and she goes down well at 7:30 and was usually sleeping through until 6 or 7 am, occasionally waking once for an extra feed between 2 or 4am. She also got her two front bottom teeth at 7 months and had a few days of fussy behavior but that usually went away pretty quickly.
Two weeks ago I switched her over two stage 2 non HA formula and I expected that things would be off for a few days but she hasn't been the same since. She fusses at every feed and some days won't drink more than 350ml all day. She's still having regular wet nappies but I'm still worried be that she's drinking so little. Her poos have also become dry and solid. (sorry TMI!) I thought she might be teething again but this fussiness has lasted two weeks and I don't see any other signs of new teeth. She's getting harder to put down for naps, doesn't want to be wrapped but when I take her arms out or put her in a gro bag she just rolls around and it's impossible to get her to sleep. At night her sleep has really deteriorated. Last night she woke at 12 and didn't go back to sleep properly until 5am! Then she woke again at 7am. This has been happening every night this week. She just cries but doesn't want to be fed, Panadol doesn't seem to help either which makes me think its not teething, and I don't want to medicate her for no reason. I took her to the doctor last week and they said she had a very small amount of fluid in her ear but didn't want to give her anything as she's so young, they said to use saline nasal spray to unblock the ear canal and go back in two weeks so I've got a doctors appointment for next week but I'm hoping someone has some advice for getting things back on track, or even just a bit of encouragement that it's normal.
If you've gotten this far thank you! And TIA for any advice/opinions.
