I have a 3 month old DD who is BF and has been since birth. I have been trying to introduce a bottle of formula a day to get her used to a bottle but either the bottle or the formula makes her very windy and unsettled so she's mostly breast fed.
My MIL is adamant she should be on solids by now. To give a bit of history neither PIL saw DD until a few weeks ago out of their own choice so they have not been involved in her life despite living fairly locally. Since the 2nd occasion that my MIL met DD she has been trying to tell me how I should feed her, that I should be giving her puréed food by now, rusks and baby rice etc. And also that she is surprised I'm 'still' breastfeeding and that she would sleep better on formula, that she would cry less etc. My DD sleeps pretty well she just still feeds in the night much to MIL's horror. She does however cry whenever she is handed round to everyone for all the cuddles people think they are entitled to. She seems to hate the pass the parcel game especially when MIL is basically a stranger to her so yes she does cry. MIL has decided it's because she's hungry and I'm not producing enough breast milk and need to give her solids. She decided all of this on the second occasion that she met DD.
MIL asked me when I was going to wean her and I said 6 months, as advised by my HV. She literally laughed in my face and said they don't know what they're talking about and that my DD won't manage on just milk until then because she's hungry already. She is adamant her children were eating roast dinners and steak by 6 months. My own DM did mention (only when I asked) that she started introducing a small amount of solids at 4 months with my siblings and I but that was the done thing 30 years ago. My MIL on the other hand will literally not let it go, and every single time my DD cries it's apparently because she wants a rusk 
Am I being precious or does she just need to get back in her box?
