Any words of wisdom appreciated . DC2s sleep was initially pretty good but the last couple of months have put pay to that (she’s now 8 months) I’m so tired some days but I find myself snapping at Older DD. She is 6, has her moments but is generally a good kid and adores her baby sister . I love her so much but this morning we were running late and I got stressed and snapped at her for not doing her teeth . Then this afternoon told her off for not putting toys away . Then for not eating her tea and saying it was too spicy (when I later tried it it actually was 
) Then she was playing with baby but it got a bit boisterous - told her once calmly but the second time raised my voice. I feel horrible this evening . I was a pretty good mum before I thought but it’s occurred to me over the past couple of months I’ve probsvky shouted at her for something every day . She doesn’t deserve it as she genuinely is a little darling, tries so hard in school and is very loving towards her baby sis . How can I get my patience back ? Is this just sleep deprivation or is being a mum of two just shouty ?! Any tips ? It’s like I’m just doing it on autopilot these days .
