Jazzcat yes the vests with poppers at bottom are for under the baby grow all in ones. Since we will be having babies in winter you may want to look at the vests with long sleeves I think most of my DD and DS were to begin with as they were both winter babies too. This just gives them a bit more layers and warmth encase their little arms escape being swaddled (if you are swaddling). I love swaddling and so did my babies so will be doing that again.
You will probably want one if those all in one snow suit thingy's as it will be too cold for just a coat I guess.
With regards to the sleep bag you wouldn't use that when they are really tiny new norms as swaddling and a blanket over top is usually best. But those sleeping bags come in really handy when they start getting more active and kick the covers off. I can't remember exactly but I think I used them from 6 months they were amazing and yes I had a spare as leaky nappies or puking milk often meant it needed to be washed a lot.
I think my baby is having a party this morning I have been feeling it flutter around for the past 30mins. marzipanned I think it was you that shared your concern with not feeling it move yet. Just for reassurance I did not feel my first until 20 weeks so please don't worry. Even the feelings of movement I am having now I think if I hadn't had children before I wouldn't realise it was baby, it is gentle fluttering not big movements.
I may have lost count since the Sonographer changed my dates but I think I am 14+4
Ooh and chapagne welcome back! Sorry you are still sick I am still on that boat with you, hoping to get off sooner rather than later.
