Please OP do NOT say that you are ONLY a SAHM! A SAHM has an incredible amount of responsibility on their shoulders, for example, you have to feed, wash, dress, change nappies, ensure LO gets all of their needs seen to, and above all keep them safe! You are also likely to be cleaning the house, doing the washing, doing the shopping, cooking meals, ironing, possibly feeding pets, walking pets, cleaning up after pets, and some of us even get conned into doing the garden too, oh and that's not to mention all the household admin that you get to do, together with arranging appointments for workmen to come in if necessary, the washing machine to be fixed if it breaks. The list goes on, and on, and on, OP. So, next time someone asks you what you do, tell them that you're a captain of industry, as effectively, that's what you are!😋
Oh, and try not to swear at your baby again, but under the same circumstances, I'm sure we have all done similar, albeit possibly without the swear words, but I think anyone who says they've never cussed at their child is probably fibbing, because like you, we all feel guilty!
