Aha, it's not "people", it's your mom!
I can't imagine a circumstance--the sky falling?--under which my mom would leave me alone about anything.
She visited over the weekend, and the whole time bugged me about getting a crib, feeding solids, etc. etc.
This evening she phoned to let us know that she and my dad got back okay and to thank us for the lovely time. She used the opportunity to tell me her thoughts about introducing solids, again.
I am not a patient woman. I told her, "Look, Mom, you don't have a leg to stand on here. You started me on solids at four weeks! That's clearly out of line. I am the one who has done all the research, you haven't read anything since the mid 1960s on this subject. So I don't want any advice from you. You should be asking me what I think, since I'm the one who has done all the reading."
Not that I'm advocating such a confrontational approach. I wouldn't call it an approach so much as a flying off the handle.
But back to you, i_o_f. After all, this is your thread! Does your mom really want you to
force your nice baby to do things? What does she mean by "force"? Hmmm? Is it an important part of her parenting philosophy that you should FORCE the baby to eat? Can you also force him to sleep? Would that make her feel better, if you started forcing the baby to do things? I didn't think so.
Probably someone else is telling her about their grandchild who eats big helpings of kale and sleeps 12 hours. Nothing you can do about that.
So ask her about how she did it with you and your siblings, and what her mom said to her, and what her MIL said, etc. Let her talk about that. Try to be kinder to your mother than I am to mine, because you only have the one mother. (In my case, thankfully!
