Hi and welcome! My DS is/was similar, slept well at night and terrible at daytime naps. He's recently started waking more at night (the dreaded 4-5mo sleep regression?) but naps seem to have improved thankfully. I've been watching him like a hawk for tired signs and encouraging him to sleep as soon as I see them, or if he's been awake for 1.5-2 hours. I also introduced a muslin comfort blanket and that seems to have helped (put it between us when feeding so it smells of me and then give it to him when he's falling asleep). He still doesn't sleep for very long in the day - usually 30-45mins and occasionally longer if we're lucky. And sleeps longer in my arms than if I put him down!

I'm impressed that you've managed to get any work done without childcare! Do you mostly do it when your DP is around to take the baby? Or were you doing work during nap times?
I think nursery (and childminder) waiting times depend where you live - they get very booked up where I am, so we booked a place before DS was born! But you might be lucky, maybe spaces will become available in September with children starting school.

I tried putting the car seat in a shallow trolley but you don't get much room at all for shopping! Recently I used the Ergobaby which was better although DS is so darn heavy (9.2kg at recent weigh-in) and it was a bit tricky getting things on lower shelves!! I also had a sore back afterwards which I think was from carrying him around the supermarket and lifting the shopping bags. Next time I'll try a trolley with a baby seat attached. He's holding his head up in the pushchair and high chair (tested recently!) so I guess he'll be fine in it.

How rude of your sister, it's none of her business and not her place to judge 
Sorry she made you feel upset and guilty. I think if you choose a good nursery the baby will be fine, and it's only 2 days a week so she will still get lots of time with you 
I definitely have mixed feelings about going back to work, even though I know it's the right choice for me! I think I will enjoy doing paid work again. It's part time (3 days) and DH will go down to 4 days a week, so DS will only be in nursery for 2 days (same as your DD Mother ) I think it will be a good balance for all us. Despite all that I am still feeing a bit emotional and nervous at the thought of leaving him to go back to work! I guess that must happen whenever you go back, however old the baby is, and it's probably just a necessary hurdle you have to go through... maybe it won't be as bad as we fear! My plan has always been to go back sometime in November although I need to confirm dates. I'm feeling reluctant to do that but maybe I'll feel better when it's organised. My main worry is DS taking a bottle (he's been refusing it again lately) but at least he'll be on solids by then. And maybe he'll drink milk from a sippy cup or something!
